1. to single tables of data, the main table of coordination, the main table of coordination and subordinate sublist, two layers of subordinate incidence relation table And three layers of subordinate incidence relation table record are inquired or are edited；

2. guaranteeing data consistency to simplify data inputting, single tables of data, the main table of coordination, two layers of subordinate are closed Join relation table and three layers of subordinate incidence relation table increase newly when recording, uses table record in source as the data of the newly-increased record of these tables Source；

3. to accelerate to use concordance list when table record calls speed, table record queries to single tables of data or editor；

4. single tables of data by system control table regulation sorting field, summarize field and field summarized manner, to table record Random assortment is carried out to summarize；

5. single tables of data record provides sorting field by system control table, table is recorded and carries out random assortment inquiry；

6. single tables of data is provided the date field of ' counting by the period ' by system control table, table record was carried out by the period It counts and summarizes；

7. single tables of data selects one or more record as certain purposes as needed by user；

8. single tables of data is provided the time that ' substantial definition field ' and storage ' entity state change by system control table ' Field name inquires entity state and state of each entity before any deadline and changes the time；

9. ' judging value phase by as defined in system control table to a certain record that user in single tables of data chooses at random Deng field name ' and ' field value comparison condition ' find out other relative recordings in the tables of data.

The form types used according to database application system menu classify by the following method to menu widget packet:

1. forms method of calling is divided into following 6 kinds:

● entree unitary call；

● button menu calls, i.e., window function button calls；

● paging menu call is called by paging menu identity, each paging menu identity uses a forms；

● OLE calls forms；

● third party software embedded functional calls forms；

● the self-editing executable program of user calls forms.

2. the data type that forms use is divided into following 4 kinds:

● only use the numerical value, character, date type-word segment data of tables of data；

● only use the big binary word segment data of tables of data；

● use the numerical value of tables of data, character, date type-word segment data and big binary field image data；

● use file data.

3. forms form is divided into following 6 kinds:

● unirecord forms: the resume formula forms of a tables of data；

● optional unirecord forms: in same menu, the inhomogeneity record of a tables of data uses different unirecord windows Body；

● record forms: a plurality of record forms that a tables of data is shown by row more；

● it records forms with gauge outfit more: placing a plurality of record field value phase under single main table level-one index in forms top Same field, forms lower part are taken a plurality of record of different value fields by row placement；

● more forms under upper list: main list record is placed on forms top, and lower part places sublist by row and is subordinated to the record A plurality of record；Or sublist unirecord is placed on forms top, lower part is placed a plurality of record that sublist is subordinated to the record by row；

● left and right forms: forms or so are respectively placed and record forms more one, for selecting record to be used as certain purposes,

Left side record forms to be selected, record forms are chosen on the right.

Specific embodiment

In order to further appreciate that the contents of the present invention, the present invention is described in detail below.

Menu widget packet

1, the Data Management Analysis of database application system:

The data that database application system uses are divided into two major classes by storage mode: one kind is with the storage of data sheet form Data in database, referred to as database data, another kind of is file data.

Database data is divided into the big binary word segment data (data such as text, figure, image, sound) of tables of data again, Two kinds of field data (numeric type, character type, date type data) is often used with tables of data.

Use to file data generallys use management data table filename, according to filename and file store path tune With the method for file data.

Database application system is made of function menu one by one, any function menu of application system, no Be outside different one or more of the data type of these types is read out from database or file storage medium it is aobvious Show computer screen, i.e., browsed or edited on term ' forms ', then carry out some back-end data processing work, finally will Implementing result is saved in database or file.

2, the tables of data interrelational form that menu uses:

Any menu of database application system may use single tables of data, it is also possible to using multiple with incidence relation Tables of data, classification method are as follows:

1. single tables of data, also referred to as ' single main table '.

2. two layers of subordinate incidence relation table: referred to as ' boss's table '；Two layers of table is referred to as ' main table ' and ' sublist ', sublist are The subordinate list of main table, a plurality of record of sublist are subordinated to a record of main table；Subordinate list can be one or more, be multiple When be known as ' and subtabulation '.

Example: substation's record on duty: being main table, each value by field definitions such as power transformation station name, shift on duty, dates on duty Logging multiple attribute fields, such as working time, action be defined as sublist；Then a certain value some day in sublist A plurality of logging be subordinated to one of main table record.

3. three layers of subordinate incidence relation table: referred to as ' boss, sublist '；Three layers of table be referred to as ' main table ', ' sublist ', ' sublist ', sublist are the subordinate list of main table, and a plurality of record of sublist is subordinated to a record of main table, and sublist is sublist Subordinate list, a plurality of record of sublist are subordinated to a record of sublist；Subordinate list can be one or more, and sublist is multiple When be known as ' and subtabulation ', be known as ' arranged side by side sublist ' when sublist is multiple.

4. the main table of coordination: single tables of data, literary name section is more, and different fields uses different forms, in order to Design is convenient, accelerates meter reading writing speed, is broken down into multiple tables；One of table is known as ' main table ', remaining multiple table Referred to as ' main table arranged side by side ', the record number of each table is identical as main table record number in main table side by side, and each record pair It should one of main table record.

Example: annual work summarizes the page for being divided into multiple fixations, every page have it is different summarize project, use a tables of data Field is too many when preservation, calls speed slow；Using summarizing one tables of data of item setup and solve this problem to every page, The tables of data record that each page uses simultaneously carries out unified call according to incidence relation again.

5. the main table of coordination and subordinate sublist: one or more sublists are subordinated to the main table in the main table of coordination, son The a plurality of record of table is subordinated to a record of main table；It is known as ' and subtabulation ' when sublist is multiple.

6. index incidence relation table: a tables of data is application system base data table, such as ' the name set table of object ' or ' the name set table of people ', another table are the fructification attribute description table of all entities of base data table record, table note Item number is recorded far more than base data table record strip number；Base data table is known as ' concordance list ', fructification attribute description table is known as ' main table '；Speed is called in order to accelerate main table record, concordance list is used to describe the key value of entity as indexing, according to two Table describes the equal incidence relation of key value that entity uses and calls main table record, referred to as ' index incidence relation '.

Example: there are several hundred transmission lines of electricity in certain power supply company, stores line properties using tables of data ' transmission line of electricity title table '； Every route has tens bases to several hundred base shaft towers, stores shaft tower attribute using tables of data ' shaft tower detail list '；Shaft tower detail list can There can be tens of thousands of records, it is slow several times when calling directly；When inquiring shaft tower attribute, by ' transmission line of electricity title table ' as index Table, ' shaft tower detail list ' are used as main table, and line name calls shaft tower detail as index key, according to selected line name The shaft tower of table corresponding line records, then record is few, calls speed fast.

7. source incidence relation table: using ' base data table ' record of some application systems or ' industry standard tables of data ' The data source as the newly-increased record of other tables of data is recorded, to accelerate input speed and guarantee data consistency, these bases Plinth tables of data or industry standard tables of data are referred to as ' source table '；It is closed when execution according to source table and by the association between editor's table Source table record calls in system, referred to as ' source incidence relation '.

Example: being used as source table for tables of data ' name doctor prescription table ', calls ' name according to the doctor of patient's prescription name and prescription name Cure prescription table ' record, it increases the data source of record when as input patient's prescription newly, then can accelerate input speed and guarantee data Consistency.

3, usage mode of the menu to tables of data:

Menu is divided into following 9 kinds to the usage mode of tables of data:

1. to single tables of data, the main table of coordination, the main table of coordination and subordinate sublist, two layers of subordinate incidence relation table Or three layers of subordinate incidence relation table table record are inquired or are edited.

2. guaranteeing data consistency to simplify data inputting, single tables of data, the main table of coordination, subordinate association are closed When main table, sublist or the sublist of system increase record newly, use table record in source as the data source of the newly-increased record of these tables；It can Primary newly-increased source table meets the record of the record number of system control table rated condition, or the source table record chosen at random Several records；And provided according to system control table, copy one or more field values of source table respective record to these tables The corresponding field of newly-increased record.

Example: aforementioned input patient's prescription, after certain prescription for selecting ' name doctor prescription table ' certain to cure, by multiple in prescription or Whole medicinal material title records increase patient's prescription table newly, and copy the quantity and unit price of selected medicinal material.

3. to accelerate to use concordance list when table record calls speed, table record queries to single tables of data or editor.

4. single tables of data by system control table regulation sorting field, summarize field and field summarized manner, to table record Random assortment is carried out to summarize；The one or more sorting fields being randomly assigned when execution by user, take not according to sorting field With value, or the classification value or classification value range that are randomly assigned, carries out statistic of classification and summarize.

Example: substation equipment account, sorting field are as follows: power transformation station name, device class (main transformer, sf6 breaker, oil-break Device, vacuum circuit breaker, voltage transformer, current transformer etc.), summarizing field is ' original value of the equipment ', and summarized manner is ' summation '； When the sorting field that user specifies is power transformation station name, then each substation's tabulating equipment initial value is pressed；When specified category words When section is device class, then each device class tabulating equipment initial value is pressed；When selecting a certain substation and make device class When for specified sorting field, then summarize all original values of the equipment of the substation by device class.

5. single tables of data record provides sorting field by system control table, table is recorded and carries out random assortment inquiry；It holds The classification value or value range for the one or more sorting fields being randomly assigned when row by user are inquired by classification；

Illustrate: random assortment inquiry summarizes that the classification method that uses is identical with random assortment, but obtain the result is that satisfaction The tables of data of querying condition records.

6. single tables of data is provided the date field of ' counting by the period ' by system control table, table record was carried out by the period It counts and summarizes；Remember when execution by the tables of data that user obtains meeting period condition to the when segment limit that the field is randomly assigned Record, and execute and calculating is summarized to close item purpose as defined in system control table.

Example: to a certain tables of data automatically generate annual, monthly, season, ten days, week, day statistical report form or stochastic inputs when Between interval stats report.

7. single tables of data selects one or more record as certain purposes as needed by user.

Example: when editor's outbound list, the goods and materials recalled are needed to pick out by some in warehouse.

8. single tables of data is provided the time that ' entity classification field ' and storage ' entity state change by system control table ' Field name, according to entity classification field determine table record substantial definition method, inquire each entity any deadline it Preceding entity state and state change the time.

Example: specified time is certain moon in year, when statistics ' substation's Load Shedding According To Frequency device throwing move back table ' ends the end of month ' state is moved back in throwing ' and ' time of origin thrown or moved back for the last time ' of all Load Shedding According To Frequency devices of substation, here, ' substation Name ' and ' Load Shedding According To Frequency device name ' be entity classification field, ' time of origin thrown or moved back ' be ' entity state change when Between ' field.

9. ' judging value phase by as defined in system control table to a certain record that user in single tables of data chooses at random Deng field name ' and system control table as defined in ' field value comparison condition ' find out other relative recordings in the tables of data, hold The a certain work of row.

Example: in ' in customer order table ', choosing a certain order record of a certain client at random, inquires this order of client hair All order records before phase birthday；Here, ' customer name ' is to judge the equal field name of value, ' order date of occurrence it Before ' it is defined field value comparison condition.

4, the form types that menu uses:

Menu forms are divided by following ' forms method of calling ', ' data type that forms use ', ' forms form ' Class, referred to as ' form types that menu uses '；

1. forms method of calling is divided into following 6 kinds:

● entree unitary call, referred to as ' main menu forms '；

● button menu calls, i.e., window function button calls, referred to as ' button menu forms '；

● paging menu call is called by paging menu identity, referred to as ' paging forms '；Example: as aforementioned annual work summarizes There is the page of multiple fixations, every page has one ' Page Name ', and ' Page Name ' is used as each page of menu call, each A page uses a paging forms；

● OLE calls forms；Example: CAD diagram, the forms that WORD document etc. uses are called.

● third party software embedded functional calls forms；Example: a certain menu of application system is soft using GIS-Geographic Information System The map forms being embedded in when part.

● the self-editing executable program of user calls forms.

2. the data type that forms use is divided into following 4 kinds:

● only use the numerical value, character, date type-word segment data of tables of data；

● only use the big binary word segment data of tables of data；

● use the numerical value of tables of data, character, date type-word segment data and big binary field image data；

Example:

Resume is embedded in photo；

● use file data.

3. forms form is divided into following 6 kinds:

● the resume formula forms of a tables of data, forms only use tables of data one record, referred to as ' unirecord window Body ', referred to as ' list '；

● in same menu, the inhomogeneity record of a tables of data uses different unirecord forms, referred to as ' can menu note Record forms ', referred to as ' menu '；Be divided into using index value menu, double click record more in a certain record, according to this record it is a certain Defined two kinds of field value menu；

Example: the device type of substation equipment account includes main transformer, breaker etc., and the account parameter of main transformer and breaker is not Together, using different unirecord forms；When editor, inquiry substation equipment account, if main transformer, main transformer unirecord window is used Body uses breaker unirecord forms if breaker；

● a tables of data is by a plurality of record forms of row display, referred to as ' mostly record forms ', referred to as ' more '；It can ring simultaneously It answers ' double click records event ' to call more and corresponding unirecord forms or optional unirecord forms is recorded by double-click, respond ' mouse Mark, which is clicked, returns to more record button ' events, returns to more record forms；

● place the identical field of a plurality of record field value under single main table level-one index, forms lower part in forms top The a plurality of record of different value fields, referred to as ' band gauge outfit records forms more ', referred to as ' taking the lead ', forms top are taken by row placement more Field is known as ' gauge outfit '；

' double click records more ' event calling can be responded simultaneously, corresponding unirecord forms are recorded by double-click, respond ' mouse Mark, which is clicked, returns to more record button ' events, returns to band gauge outfit and records forms more；

Example: when by department's inquiry, printing employee's register, department's name is placed on forms top, same portion as gauge outfit The a plurality of record of door employee is placed on forms lower part by row.

● main list record is placed on forms top, and lower part is placed a plurality of record that sublist is subordinated to the record by row；Or window Sublist unirecord is placed on body top, and lower part is placed a plurality of record that sublist is subordinated to the record by row；Referred to as ' above more windows under list Body ', referred to as ' upper single lower more '；

' double click records more ' event calling can be responded simultaneously, corresponding unirecord forms are recorded by double-click, respond ' mouse Mark clicks more record button ' events that return, more forms under list in return；Or response ' double click mostly record ' event calling is double It hits and records corresponding button menu forms, response ' mouse-click return main menu button ' event, more forms under list in return；

Example: such as aforementioned substation record on duty, the power transformation station name, shift on duty, date on duty of main table are placed in forms top Etc. fields, lower part a plurality of logging of each value is placed by row；

● forms or so are respectively placed and record forms more one, and for selecting record to be used as certain purposes, the left side is waited for

Choosing record forms, record forms, referred to as ' left and right forms ' are chosen in the right；

Response ' double click record ' event make to be recorded between the forms of left and right and move (the double-click a certain record of left side forms, The record moves to the right forms, double-clicks the right a certain record of forms, which moves to left side forms)；It can once select as needed Select one in the record forms to be selected of the left side, it is a plurality of or all record as choosing record, move on on the right of choose record forms；

Same tables of data can be used in two forms, it is possible to use different data table；

Example: such as aforementioned editor's outbound list, left side forms are that optional goods and materials record, the right forms are that goods and materials is chosen to remember in warehouse The a certain goods and materials record of record, the double click left side or the right forms, which executes, to be chosen or abandons.

5, menu widget packet design principle:

Above-mentioned ' the tables of data interrelational form that menu uses ', ' usage mode of the menu to tables of data ', ' window that menu uses Body type ', it is the classification method that development platform executes data processing to menu, referred to as ' menu data processing type '.

Development platform classifies to database application system menu by menu data processing type, and every one kind menu uses One execution module, referred to as ' menu widget packet '.

Menu widget packet uses the design method similar to function, and call parameters are deposited using the system control table of development platform Storage, application system read these parameters when running, dynamic generation executes code, complete menu function.

Menu widget packet is the execution module based on menu data processing type level exploitation, so, database application system The same menu widget packet can be used in all menus of same data processing type in subordination, realizes module reuse requirement.

6, Specification Design requirement of the menu widget packet to tables of data:

Call speed and in order to accelerate table record convenient for the design of menu widget packet, tables of data of the development platform to application system There is Specification Design requirement below:

1. major key (primary key) and external key (foreign key) are defined as to all tables of data that menu uses Integer type, and as follows using unified major key, external key and main external key correlating method, design method:

Single main table, main table, side by side main table, unique major key xuhao；

Sublist and subtabulation, two major keys xuhao, xuhao1；

Sublist, side by side sublist, three major keys xuhao, xuhao1, xuhao2；

Sublist, simultaneously subtabulation, side by side main off-balancesheet key are main table major key xuhao；

Sublist, side by side sublist external key are sublist major key xuhao, xuhao1；

Major key xuhao, xuhao1, xuhao2 are defined as integer type.

2. subordinate incidence relation table (boss's table, boss, sublist), the main table of coordination, the main table of coordination and subordinate Sublist is deleted according to table record of the main external key to subordinate list and main table arranged side by side using cascade；It indexes incidence relation table and source is closed Join relation table to delete without using cascade.

3. increasing two values type-word section, a character type field and one to the various types tables of data that menu uses A date type-word section, and unified field name is used, for storing the human editor identity of the newly-increased record of tables of data and increasing record newly Date, the field name used are as follows:

Ejbmbh1: the industry number of human editor；Bzbh: teams and groups' number of human editor；Operator: the personnel of human editor Number；Operdate: newly-increased record date；

The first two is numeric type field, and operdate is date type-word section, and operator is character type field；

When newly-increased table record, aforementioned four field value is set with the personal part of login and system time, for personal by operation Part filter table record or other functions use.

System control table

1, the design principle of system control table

The whole design thought of development platform is using the design method similar to function, by the institute of database application system Functional module design is the execution pattern that the parameter stored by outer carrier is called.

The system function of database application system is made of function menu one by one, any moment of system operation, Any one user is only possible to use a function menu, belongs to discrete way operation.The record format of relational database tables of data, It can satisfy the parameter designing requirement of database application system menu discrete way operation.

Development platform is by the multiple tables of data of the relational database of memory function module call parameters, referred to as ' system control Table ', the design to system control table has following 3 basic demands:

1. the needs of parameter designed meets description application system architecture and executes menu widget packet；

2. the definition of parameter should not have an ambiguity, whens calling functional modules is unique to the explanation of these parameters；

3. the editor and modification to parameter are convenient.

2, database application system architecture characterising parameter and menu function characterising parameter avoid ambiguous design side Method:

(i) database application system architecture characterising parameter and menu function characterising parameter fundamental type are divided into: non-to enumerate Shape parameter enumerates shape parameter and three kinds of expression argument, is described as follows:

1. non-shape parameter of enumerating includes numeric parameter and two kinds of string argument, numeric parameter is defined using integer, character String parameter is defined using character string；For example, the record line number of mostly record forms is defined using integer, menu identity, what menu used Data table name etc. is defined using character string.

2. enumerating shape parameter: the value number of parameter is denumerable, then parameter enumeration type parameter definition；Enumerate shape parameter Value is defined using the integer serial number of mark enumerated value.

Example: ' menu background process processing method table ' write record mode is divided into six kinds, is described as follows with shape parameter is enumerated: 0 Judge whether to exit calling, 1 newly-increased record, 2 modification records, 3 deletion records, 4 have record modification, and no record is newly-increased, and 5 call number According to library process；Serial number: 0,1,2,3,4,5 definition is enumerated in parameter value use；Such as: being ' increasing record newly ' when parameter value is equal to 1, compiling Ambiguity will not be generated when collecting parameter and module calling.

3. expression argument: defining that method is identical with expression formula used in database SQL sentence, as tables of data records Filter condition expression formula.

(ii) as follows to the concrete regulation of parameter definition:

First: non-enumeration type numeric parameter integer or integer sequence define, and the integer in integer sequence uses agreement point It is separated every symbol.

Second: non-enumeration type string argument character string, character string sequence or text definition；Wherein character string sequence is used It is separated between multiple character strings, character string with agreement separator.

Example: the data table name that menu uses is defined with character string；What multiple index field names of tables of data were separated with comma Character string sequence definition；Text definition is used in the operation help of menu.

Third: the integer definition that shape parameter mark enumerates serial number is enumerated.

4th: parameter is conditional expression, date expression formula, numerical expression, character expression, statistics calculation expression When, it is defined using the corresponding expression formula in database SQL sentence；Referred to as ' expression argument '.

5th: when a parameter uses multiple enumeration type subparameters, referred to as ' enumeration type subparameter ', with integer sequence or The parameter is defined with an integer；When being defined with integer sequence, subparameter number is equal to the integer number of integer sequence, integer It is separated between integer in sequence using agreement separator, the corresponding subparameter of each integer；When being defined with an integer, Subparameter number is equal to the digit of integer, and each of integer corresponds to a subparameter；Note that when being defined using an integer, Enumerated value is no more than 9.

Example 1: shape parameter: 1 ascending order, 2 descendings are enumerated in the sequence use of tables of data record, and define multiple words with an integer Section sort method；When being sorted using a field, parameter is 1 integer；When being sorted using two fields, parameter is two whole Number, ten bit identification first character section sort methods of integer, second field sort method of a bit identification；A certain tables of data has two A sort field: field1, field2, field field1 sort in descending order, and field field2 is sorted in ascending order, then parameter uses Integer ' 21 ' identifies.

Example 2: shape parameter is enumerated in date field indexed mode use: 1 year, 2 half a year, and the third quarter, April, 5 half a months, 6 ten days, 7 weeks, 8 days, 9 time-divisions, and defined with integer sequence；A certain tables of data has a date index field datel, and the first order indexes rope per year Draw, second level index per diem indexes, then parameter is identified using integer sequence ' 1,8 '.

Six: one parameter using it is multiple it is available enumerate shape parameter when, referred to as ' enumeration type optional parameters ', using not The digit of 01 sequence definition of number with separator, 01 sequence is equal to optional parameters number, each corresponds to 1 optional parameters, A certain position is equal to 1, and mark uses this corresponding optional parameters, is equal to 0, mark does not use this corresponding optional ginseng Number.

Example: table records Edit button and uses 8 bit digital, 01 sequence definition, the corresponding Edit button rule of each of 01 sequence Be set to: 1 increases main table record newly, and 2 delete main table record, and 3 newly-increased sublist records, 4 delete sublist record, and 5 increase sublist record newly, 6 delete sublist record, and 7 save, and 8 abandon editing；

When a certain position of 8 bit digital, 01 sequence is equal to 1, then using the corresponding Edit button of this, a certain position is equal to 0, then not Use the corresponding Edit button of this.Such as: 01 sequence definition is ' 11000011 ', then the Edit button used are as follows: increase main table newly Record deletes main table record, saves, abandon editing.

Seven: one parameter uses multiple subparameters, subparameter can with right and wrong enumeration type parameter, enumerate shape parameter or expression Formula parameter is separated between subparameter, referred to as ' combination parameter ' with the separator of agreement.

8th: if a certain subparameter is defined using character string, character string sequence, integer sequence or expression formula in combination parameter When, they are included using the identifier of agreement, is labeled as a subparameter.

9th: the parameter described with combination parameter there are two types of and when two or more different usages, by each user The combination parameter of method is included using the identifier of agreement, is separated between method with the separator of agreement.

Example: menu forms date type-word section display format is defined as: [table class, { year field list of file names }, { days field name List }, { date field list of file names }, { time-division date field list of file names }]；

Wherein ' table class ' is enumeration type subparameter, is seen below ' system control table is common to enumerate shape parameter ', minor ginseng Number is defined with the character string sequence that { } includes；The format parameter of each table class of menu forms is included with [], the lattice of multiple table classes Formula parameter is separated with comma.

Tenth: system control table is common to enumerate shape parameter:

' 1. table class ', the tables of data or execute the tables of data that reading and writing operate with that menu forms use: 1 main table, 2 sublists, 3 sublists, 4 source tables, 5 main tables arranged side by side, 6 and subtabulation, 7 sublists arranged side by side, 8 button menus newly newly lead by main table, 9 button menus Sublist, 10 left side menu widget packet W_zhu_xz_zhu forms tables.

Illustrate: the data table name that menu uses is in system control table with corresponding ' table name ' parameter identification, menu forms The tables of data that the tables of data or execution reading and writing used operates with is identified with ' table class ', calls corresponding data according to ' table class ' Table；Such as: table class is equal to 1, then the tables of data for calling ' main table name ' to identify.

' 2. public variable ', the global variable of preservation login personal part when application system is run: 1 department name, 2 teams and groups name, 3 Name, 4 teams and groups' classes, 5 shifts on duty, 6 system datas, 7 system times, 8 tier-2 departments name, the set name of the object of 9 management, 10 pipes The set name of the people of reason, 11 department's classes, 12 logs number taken turns at keeping watch, departments No. 13, teams and groups No. 14,15 unit names.

3, system control table master-plan

The data processing object of database application system is divided into four layers: function menu, tables of data, table record, literary name section；System System process is divided into two major classes: foreground process and background process；System control table is exactly by this four layer data of database application system Processing and the different of two class system process require setting processing parameter.The parameter that system control table stores is divided into three greatly when design Class: system master parameter, system secondary control parameter, the processing of menu background process execute method parameter；Wherein preceding two class belongs to The execution method parameter of application system architecture characterising parameter and the utility function for calling menu widget Bao Shiying to realize, it is latter Class is to complete the execution method parameter of menu background process specific function processing.

System master parameter is stored using a tables of data, referred to as ' system controls main table '；

System secondary control parameter is stored using six tables of data, is respectively as follows: that ' menu priority assignation table ', ' table recorded Filtering method table ', ' Select input method table ', ' management Object table ', ' tables of data major key xuhao maximum value table ', ' tables of data Record export introduction method table '；

Menu background process processing method parameter is stored by ' menu background process processing method table '.

Each system control table major key is defined as integer type；

Control the major key of main table by system: menu serial number, menu forms serial number, second level paging menu serial number and other Control table is associated, and tables of data record filtering that menu operation permission when for executing menu, menu use, editor call Call parameters when Select input, calling background process processing.

4, system controls main table design

4.1 menu categories and major key

The menu that database application system uses is divided into three classes: main menu, button menu, paging menu.

But only one main menu of any menu；It also may include a main menu and multiple buttons menu；Or include one Main menu and multiple paging menus；Paging menu can also have multiple second level paging menus；Paging menu and button menu are referred to as ' son Menu '.

Major key totally 3: menu serial number, menu forms serial number, second level paging menu serial number.

' menu serial number ' is for identifying different main menus；Belong to the multiple buttons menu or paging menu of same main menu It is distinguished with ' menu forms serial number ', ' menu serial number ' is identical as main menu；Second level paging menu uses ' second level paging menu serial number ' It distinguishes, ' menu serial number ' is identical as main menu, and ' menu forms serial number ' is identical as paging menu.

The menu forms serial number regulation of main menu is equal to 1, and the menu forms serial number regulation of submenu is greater than 1.

When application system is run, the entree unirecord that system control table menu forms serial number is equal to 1 is first carried out, then again Executive button menu or paging menu；If the menu under a certain ' menu serial number ' without ' menu forms serial number ' equal to 1 records, neglect Slightly it is somebody's turn to do whole records of ' menu serial number '；The menu forms serial number of main menu can be set smaller than or be equal to 0, mark entree List and the submenu of subordinate wouldn't use, if wanting to enable the menu, which is changed to 1；If but deleting a certain menu Record, to reactivate, then must update menu parameter.

4.2 menu identity parameters and operation instruction

The parameter used: further menu name, second-level menu name, three-stage menu name, level Four menu identity, Pyatyi menu identity, and Menu sequencing methods at different levels；Pad name and sort method；Button menu or paging menu identity；Second level paging menu identity.

Menu must have pad name, and preceding Pyatyi menu can be set as needed；When application system is run, further menu, Second-level menu, three-stage menu, level Four menu, Pyatyi menu, main menu and paging menu will automatically generate dish according to sort method Single index tree；Button menu name is placed on the function button area above main menu forms automatically；Second level paging menu identity is placed on automatically Above paging forms.

All menu identities are defined with character string；Preceding Pyatyi menu and main menu index order method are defined with integer；Point Page menu index is sorted with major key menu forms serial number.

4.3 menus execute method, use 4 parameter definitions:

1. menu executive mode is divided into three kinds: 1 calling development platform menu widget packets, 2 third party software embedded functionals It calls, 3 self-editing executable programs call.

The function button of 4.7 menus designs:

Function button is divided into: Edit button, background process call buttons, 0LE funcall button, button menu forms tune With five kinds of button, menu operation help button；

1. Edit button and background process call buttons totally 10: increasing main table record newly, delete main table record, increase sublist newly Record deletes sublist record, increases sublist record newly, deletes sublist record, saves, abandon editing, main literary name segment value decomposes Automatically newly-increased sublist record, background process call.

Whether they use the optional subparameter of enumeration type, used by the corresponding button of 10 01 sequence identifiers；When first When equal to 2, identifies main table and sublist and increase record newly simultaneously；Main table arranged side by side is without using ' newly-increased record ' and ' deletion record ' button； And subtabulation, sublist arranged side by side use sublist, sublist Edit button.

10 button names are defined with character string sequence；Button name can rename as needed.

Note 1: it after having input main table a certain field value, clicks ' main literary name segment value decomposes newly-increased sublist record automatically ' and presses Button then decomposes the character string sequence of field input, increases newly automatically and identical number scale of character string number of decomposition to sublist Record, and decomposition value is placed in defined field；

Note 2: ' background process calling ' button be ' further work process title ' button, such as: after ' notice ' editor ' issuing a notice ' etc.；Click the button, then call ' menu background process processing method table ' menu record, execute menu under The processing of one process；

Note 3: this 10 buttons can rename as needed, and it is constant to execute method.

2. totally 5, OLE funcall button: selecting disk file, file data is stored in the big binary field of tables of data, browsing The big binary data of tables of data, big binary data save as new file, return to the main menu page；

Identify whether corresponding funcall button uses using the optional subparameter of 5 enumeration types；

5 OLE funcall button names are defined with character string sequence；Button name can rename as needed, the side of execution Method is constant；

The other parameters of OLE funcall: ' OLE funcall takes big binary data or takes the field name of filename ', ' OLE type field ' ' path that OLE funcall takes filename ' and ' save the field of the source filename of big binary data Name ' character string identification is used respectively.

3. main menu call buttons menu forms button and button menu forms return to main menu forms button, two are used A parameter definition: ' button menu name sequence ' and ' 01 sequences of call buttons menu forms '；

' 01 sequence ' first of call buttons menu forms fills out 0 when for main menu；Second starts to fill out 1, and correspondence is each A button menu name, 1 number are equal to button menu number；

Button menu only needs first of 01 sequence to fill out 1, corresponding return main menu button name；

' button menu name sequence ' identifies its sort method simultaneously；

Button menu do not allow certain people in use, by ' button menu do not allow using condition ' parameter identification, the ginseng Number is conditional expression；Data sheet field condition or public variable condition, when using public variable condition, public variable can be used With ' management organization's table ' or ' Responsibility of Staff table ' corresponding field name mark.

4. third party software embedded functional button is defined using button menu.

' 5. the index series for opening newly-increased record button ' and ' the index series for opening background process call buttons ': being used for Provide newly-increased record button or background process call buttons allow using index series, defined respectively with integer (when open When indexing series less than defined index series, the corresponding button is in masked state).

6. shielding the regulation of other operations after clicking newly-increased record button, use combination parameter: { main table increases button shielding newly Class list }, { sublist increases the list of button shield type newly }, { sublist increases the list of button shield type newly }；

Shield type in combination parameter is identified using enumeration type argument sequence: 1 main table record increases newly and delete button, 2 sons Table record is newly-increased and delete button, 3 sublists record newly-increased and delete button, and 4 index trees, 5 button menus, 6 main tables record new Increase button, 7 sublists record newly-increased button, and 8 sublists record newly-increased button, 9 the 9th Edit buttons, and 10 background process calling is pressed Button；Without using shielding when parameter is empty.

7. shielding the condition of background process call buttons: using combination parameter: table class, { condition }；Table class is ' table class ' ginseng Number, ' condition ' are conditional expression；' background process calling ' button is shielded when condition is true.

8. whether shielding index when editor, using enumeration type parameter identification, 0 is not, and 1 is.

9. ' menu operation help ', parameter text definition, screen releases help information when clicking the button.

' 10. data flowchart ', parameter is identified with filename, releases menu data stream according to filename when clicking the button Cheng Tu.

4.8 menu forms tables record special editting function design

Totally 6 kinds of special editting functions, can be as needed using one such or a variety of；They are respectively as follows: newly-increased record It sets public variable, newly-increased record duplication, Select input is called to set field value, record editor shielding, field editing shielding and field Condition editor shielding.

1. newly-increased record sets the personal part public variable value of login, two groups of combination parameters are used:

1 format of combination parameter: [table class, and list serial number, { assignment field list of file names }, { the corresponding public change of field assignment Measure serial number list }, { the constant value list that field is assigned }]；

2 format of combination parameter: table class, and list serial number { assign management object value field name, call management Object table record Public variable class, call management Object table record management object name, read management organization's table entity attribute field column Table }, { writing management organization's entity property value list of fields }；

Wherein combination parameter 1 is used to assign the personal part public variable value of login to field and constant value, public variable are system Control table is public to enumerate shape parameter；Parameter value is equal to 0, and field assigns constant value；Parameter value is greater than 0, and field assigns public variable value；When Public variable are as follows: when the set name of the people of the set name of the object of 9 management or 10 management, alternately by the element of corresponding set Value, sets field value using method identical with Select input.

Example: assignment field list of file names is ' bdzm, xm, lb1, lb2 ', and the corresponding public variable serial number list of field assignment is ' 2,3,0,0 ', the constant value list that field is assigned is ' team or group plan, power failure work ', then when increasing record newly, will log in people's automatically ' teams and groups' name ' is assigned to field bdzm, will log in people ' name ' and is assigned to field xm, constant ' team or group plan ' is assigned to field lb1, will Constant ' power failure work ' is assigned to field lb2；

Combination parameter 2 is there are two types of usage, and first for assigning management object value to field, and value table is ' management Object table ', According to ' the public variable class for calling management Object table record ' and ' the management object name for calling management Object table record ' filtering should Table record, the management object value for reading the record are alternately worth, and are assigned using method identical with Select input to value field is write Value；Second for assigning management organization's entity property value to field, and value table is ' management organization's table ', according to login people in supervisor The corresponding record of structure table reads entity attribute field value, is assigned to write value field.

Management organization's table entity attribute field can according to need setting, such as: transformer substation voltage grade, teams and groups' number etc..

2. newly-increased record duplication, use four parameters: table record clone method, according to condition record clone method, record are multiple Literary name section is write when meter reading field, record when processed replicate, is described as follows:

● table records clone method, and totally 16 kinds, the source table and object table of record duplication are executed with enumeration type parameter identification, and The record of duplication: 0 does not replicate, and 1 main table current record copies to main table, and 2 sublist current records copy to sublist, and 3 sublists are worked as Preceding record copies to sublist, and 4 main table current records copy to sublist, and 5 sublist current records copy to sublist, 6 boss's tables All record copies to sublist for forms sublists, and all record copies to sublist for 7 sublists and sublist forms sublist, 8 main tables Sublist sublist meet the duplication of condition minute book table, 9 main literary name section decomposition values generate sublists and record more, and 10 source tables record is multiple System, 11 main table current records copy to button menu forms table, and 12 sublist current records copy to button menu forms table, 13 sons Sublist current record copies to button menu forms table, and 14 main table current records and the current record of source table copy to main table, and 44 Main table current record and the current record of source table copy to sublist, and all record copies to main table to 41 source tables；

● according to condition record duplication is served only for table record clone method 8, uses combination parameter, format: record duplication table Class, { field name for seeking maximin }, the method for seeking maximin, the public variable of the filter record, { item of filter record Part expression formula }；

Its neutron parameter ' field name for seeking maximin ' can be date type or numeric type field, ' seek minimax The method of value ', minimum with enumeration type parameter identification: 1,2 is maximum；' public variable of filter record ', with enumeration type parameter identification: 0 does not use, department No. 1, teams and groups No. 2,3 operator's names, respectively corresponds the normative field of table record: ejbmbh1, bzbh, operator；

● meter reading list of fields when record duplication: identified with character string sequence；

● literary name section list is write when record duplication: being identified with character string sequence；

Note 1: the corresponding Edit button the 9th of clone method 9: ' main literary name segment value decomposes newly-increased sublist record automatically ', main table Take decomposition value field name by meter reading field definition；The field of decomposition value write-in is defined by writing literary name section；

Note 2: the menu structure that the source table and object table and the record of duplication of 10 duplicated record of clone method are used by menu The determination of part packet need to only define meter reading field and write literary name section；

Note 3: meter reading field is corresponded with literary name section is write.

3. whether using Select input setting field value；It is identified with number 01, calls Select input when equal to 1, use selection The field name and Select input method of typing are defined by ' Select input method table '.

4. record editor's shielding, uses four parameters:

● shielding mode, with enumeration type parameter identification: 1 record editor's shielding, the shielding of 2 Row control page editings, 3 record Grouping editor's shielding；

● the shielding of mode 1,3 editor's table class and mode 1,2 condition table classes (both modes 1 are identical)

● editor's shielding condition: identified with conditional expression；

● do not allow the prompt information edited: using Text Flag.

Note 1: record editor's shielding record editor's shielding: is executed to the record of satisfaction ' editor's shielding condition '；

Note 2: Row control page editing shielding: when the unirecord that afterbody indexes meets ' editor's shielding condition ' When, to the main menu page and whole button menu page shielding editors；

Note 3: record grouping editor's shielding: the record having allows some to edit, and other people can only inquire, referred to as ' record grouping editor shielding '；Example: when professional teams and groups' recording device account, the account that can only edit this profession is recorded, but can be with Inquire the account record of other profession inputs；' the management pair read in when the editable record of grouping editor is by ' table record filtering ' As table is grouped edit condition ' it executes.

5. field editing shields, combination parameter, format: [table class, shield type, { field name sequence }] are used；Shield type is used Enumeration type parameter identification: 1 whole fields do not allow to edit, and 2 ' field name sequences ' are to allow edit field list, 3 ' field name sequences Column ' it is not allow edit field list, 4 ' field name sequences ' are the gauge outfit field column for recording forms more with gauge outfit and allowing to edit Table；

Shape parameter is enumerated in table class use, identical as the table class of some table that menu forms use.

Note: band gauge outfit records forms after editing gauge outfit field more, employs the replacement of gauge outfit field value certainly and records forms more In these field values all recorded.

6. field condition editor shields, using combination parameter, format: [condition table class, condition table serial number arranged side by side, { condition }, Mask field editor's table class, { mask field list }]；

Condition is conditional expression；Mask field list is identified with character string sequence；Condition table serial number integer ginseng arranged side by side Number；Shape parameter is enumerated in two table class uses；

Note: ' condition table class ' and ' mask field editor's table class ' can be same tables of data, be also possible to different data table, The mask field editor when condition is true.

4.9 editors must record field judgement and record uniqueness judgement when saving

1. must record field judges parameter format, it is divided into unconditional and two kinds of conditional:

● field judgement must be unconditionally recorded, judges that class is equal to 1 or 2, using combination parameter, format:

[table class judges class, executes class, { executes the control option of class 2 or executes the generation memorandum keyword choosing of class 1 , { list of fields must be recorded }, { field name annotation list must be recorded }]

● conditional must record field judgement, judge that class is equal to 4, using combination parameter, format:

[table class, judges class, { must record list of fields }, { must record field name annotation list }, condition table class, condition table arranged side by side Serial number, { condition }]；

Parameter declaration: table class, condition table class are ' table class ' parameter；Condition is conditional expression；Condition table serial number arranged side by side makes It is identified with integer；It executes class and judges that class enumerates shape parameter using following；Remaining parameter is identified using character string sequence；

Execute class: 0 does not keep records of, and 1 keeps records of, and 2 keep records of but do not execute Row control；

Judge class: 1 forms current record must unconditionally record field, and all record must unconditionally record field, 4 forms to 2 forms The judgement of current record condition must record field；

2. field arbitration functions explanation must be recorded:

It must record that field judgement is divided into ' must unconditionally record field ' and ' condition must record field ' two kind, the latter is when the condition is satisfied Judged, the former unconditionally executes judgement；

Index field to tables of data is, it is specified that for that must record field；If these field values are null, basis ' must record field Name mark ' it generates and provides prompt information, edited record is not saved；

To non-index field, if these field values are null, but allow user's typing next time, then basis ' must record field Name marks ' generation simultaneously provides prompt information, the edited record of preservation, and generates to be directed to according to ' generating memorandum keyword ' and step on The memorandum of people is recorded, shows the memorandum for logging in people after login system automatically next time；

Field must be recorded to what Row control required, it is raw according to ' field name mark must be recorded ' if these field values are null At and provide prompt information, save edited record, but do not execute flow processing as defined in ' control option '.

3. table records uniqueness or the record uniqueness judgement of menu forms, using combination parameter, format:

[table class, judges class, { record uniqueness judges key field list of file names }, { field annotation list }]；

Judge class, using enumerating shape parameter: 1 menu forms all record, and 2 tables all record；

Subparameter ' record uniqueness judges key field list ', ' field name annotation list ', use character string sequence Mark；

When subparameter ' table class ' is equal to 4, for repeating to judge using the newly-increased record of source table, field is labeled as prompt letter Breath, list of fields are newly-increased record object table field name；When not equal to 4, executed by table class.

4. recording uniqueness judgement explanation:

If the record of input is judged as not unique, is generated according to ' field name annotation list ' and provide prompt information, no Save edited record.

4.10 summarize Parameters design by period statistics

Filtering is executed by the period of stochastic inputs to specified single tables of data record, generates sublist record, and execute solid Determine project to summarize, statistical time range and summarized results are stored in main table；Table name is counted by ' come source table table name ' parameter definition；It uses 4 parameters:

1. taking time-slice method, totally 4 kinds: 1 one field identification period sections, 2 two field identification period sections, 3 are less than It is more than or equal to the time value of input equal to the time value of input, 4；

2. the date field name of main table input period；

3. the date field name that source table is summarized by the period；

4. the value classification of main table input period, totally 4 kinds: 1 years, 2 days, 3 dates, 4 time-divisions date；

1. and 4. parameter uses enumeration type parameter identification, remaining parameter character string or character string sequence mark；

Function declaration, which is shown in, ' summarizes component packet ' design method by period statistics.

Function declaration: after user clicks source table date field afterbody index, according to entity classification field and the end of term Date category generates main table end of term entity state inquiry record；' indexed mode ' and the corresponding relationship of ' end of term date category ' are shown in ' end of term entity state inquiry component packet ' design method.

4.13 lookups choose entity correlation table to record design method at random

Function declaration: a certain item is chosen to record at random single main table user, by substantial definition as defined in system control table Field value and comparison condition filter out the relative recording for choosing entity；Use a main table and a source table；Choosing record makes Table is defined with source table, and obtained relative recording is saved with main table；One forms, forms top alternatively more to be recorded, forms Relevant more record is recorded to choosing below；

Processing parameter totally two:

1. substantial definition field: being defined using source table and main table associate field；

2. comparison condition: conditional expression；

4.14 call the Parameters design of background process processing:

' background process processing ' is called to can be main menu or button menu；

Design method: system is controlled into two primary key values (menu serial number, menu forms serial number) of main table, ' is logged in The menu function button serial number ' and ' that people executes logs in the Row control option serial number that person selects ' it is used as call parameters；Latter two The parameter value of parameter is identified when being multiple using integer sequence, calls ' menu background process processing method table ' respectively when execution Difference record；Parameter designing is as follows:

● call the function button serial number of background process processing: using enumerating shape parameter: 0 is not, and 1,2,3 is main table respectively, Sublist, sublist increase record button newly；4,5,6 be main table respectively, sublist, save button when the newly-increased record of sublist；7 is main Table, sublist have save button when record；8 main tables, sublist, sublist have save button when record；9 save buttons； 10 background process call buttons；11,12,13 be main table, sublist, sub- sublist deletion record button respectively；

● Row control option list: when further work calls different background process, using list mode for stepping on Record person selects；String argument；Example: there are 3 control choosings when the checking report forms that certain grade of management organization responsible person reports next stage , be listed as follows: 1 return is rewritten；2 audits pass through；3 wouldn't determine.

● control option: log in the option serial number of ' Row control option list ' that person selects；

Such as above-mentioned ' checking report forms ', select when logging in person: ' 1 return is rewritten ' when, call parameters are used as by 1；Selection: ' 2 audits pass through ' when, call parameters are used as by 2；

● ' whether user saves former current record value when clicking newly-increased Edit button, deletion, saving as background process processing Using ' parameter, when as executing tables of data write operation, if use ' the judgement and execution parameter of former current record ' field value；

The parameter is identified using two integers: first, Edit button: 1 newly-increased 2, which deletes 3, saves；Second, table class: 1 Main 2 sublist of table, 3 sublist；Not save former current record field value when sky, when not for sky, current note is saved before user edits Record value, and the former current record field used is identified with prefix LA0_ field name in ' menu background process processing method table ' Value；Parameter value is separated when being multiple with comma.

4.15 generate Web query System Parameter Design method

After the menu editing that need to the execute Web query Web query page, Web query system can be automatically generated；Parameter is set Meter:

● Web query page name: string argument, when not for sky, using menu as Web query menu；

● according to menu definition parameter when execution, the tables of data parameter that menu uses, table index parameter, the Web query page Name parameter, dynamic generation Web query menu and the Web query page.

The editing interface of 4.16 ' system controls main table ' is shown in Fig. 2-Fig. 6.

5, table record filtering method table designs

1. major key totally 5: menu serial number, menu forms serial number, second level paging menu serial number, filter table class and filtering Recording mechanism；

Wherein first three controls main table with system to identify the keyword of menu identical, and when execution is according to keywords worth equal original Then call；' filter table class ' mark executes filtering to that table that menu uses；' filter record number ' is to distinguish different to be System logs in people and uses the different record settings of this method table.

When executing table record filtering, it is first determined log in this method table record that people uses, then joined according to corresponding record Numerical value is filtered menu data table record；When a certain login people records without corresponding this method table, menu data table is used Whole records.

2. using the following 2 identity conditions for logging in people, totally 6 parameters determine that any system logs in this method for using of people Table record:

Condition 1: identity public variable class 1, identity public variable value list 1, judgment method 1；

Condition 2: identity public variable class 2, identity public variable value list 2, judgment method 2；

' the identity public variable class ' of two conditions is to enumerate shape parameter: 1 department's class, 2 departments name, 3 classes of station classes, 4 classes of stations Name, 5 Responsibility of Staff, 6 names, 0 any login people；

When the identity public variable class of condition 2 is 0, expression only uses condition 1, and when not being 0, condition 1 and condition 2 are and Relationship；

' judgment method ' of two conditions is to enumerate shape parameter: 0 be unsatisfactory for condition be it is true, 1 to meet condition be true.

Example: if identity public variable class 1 is equal to 3, identity public variable value list 1 is ' teams and groups, substation ', judgment method 1 is equal to 1；Remembered when then a certain class's station class for logging in people is ' teams and groups ' or ' substation ' using the filter method filter table of the record Record；If judgment method 1 is equal to 0, when a certain class's station class for logging in people is not ' teams and groups ' or ' substation ', the mistake of the record is used Filtering method filter table record；

3. table record filtering method:

First: equal with corresponding data sheet field value by public variable or inclusion relation is filtered；

Second: being filtered by management object value with corresponding data sheet field value inclusion relation；

Third: above-mentioned two 16 kinds of filter methods are described with 01 argument sequence of following 16 public variables, a certain position etc. In 1, corresponding filtering is executed, is equal to 0, does not execute corresponding filtering；

16 01 sequences of public variable: 1 industry number are filtered, 2 teams and groups number, 3 log serial numbers, 4 departments name, and 5 classes Group name, 6 names, 7 shifts on duty, 8 tier-2 departments name, the set name of the object of 9 management, the set name of the people of 10 management, 11 departments Class, 12 teams and groups' classes, 13 unit names, 14 management object value filterings, 15 management object expression filterings, 16 person numbers；

Ejbmbh1, bzbh of industry number, teams and groups' number, the automatic corresponding data table of person number in public variable, Operator field；' public variable is corresponding by parameter for remaining public variable value data sheet field corresponding with management object value Data sheet field name ' it is specified；

The set name of the object of ' 9 management in public variable ', the set name of the people of ' 10 management ' it was carried out by inclusion relation Filter, remaining is filtered by relation of equality；

' 14 management object value filterings in public variable ', ' 15 management object expression filterings ', ' call and manage according to parameter The public variable class ', ' for managing object value calls the management object name of management object value ' or ' call the public of management object expression Variable class ', ' calls the management object name of management object expression ' filtering ' management Object table ' record obtains corresponding ' management Object value ' or ' management object expression '；' call the public variable class ' use of management object value and expression formula to enumerate shape parameter: 1 department name, 2 tier-2 departments, 3 teams and groups name, 4 teams and groups' classes, 5 names, 6 Responsibility of Staff；

' management object expression class ' is equal to 2, ' 15 management object expressions filterings in public variable ' expression formula be to hold Capable filter condition；When equal to 3, ' 15 management object expressions filtering ' expression formula be execute ' record editor in public variable Shielding ' in ' record grouping editor shielding ' conditional expression；

4th: by the SQL conditional expression of parameter ' filtering ', the SQL condition that given filter executes；The parameter is condition table Up to formula.

4. ' table record filtering method table ' editing interface is shown in Figure 11.

6, Select input method table designs

When to literary name segment value typing using ' Select input ' method, the chosen candidate value of Select input can be ' non-menu forms The a certain field value that a certain field value of record ' table or ' the current set of menu forms that use table use table ' table to record；It is optional to log in people Select one or more chosen candidate value write-in edit fields.

Using this method table Same Way carry out Select input field can be one or more, with ' write value field column Table ' mark；The different records of this method table are used when different field executes different Select input methods respectively.

Parameter type: when parameter is table class, using enumerating shape parameter；When for condition, use condition expression argument；For When field name, character string or character string sequence parameter are used；And list serial number uses numeric parameter.

1. major key totally 3: menu serial number, menu forms serial number and ' Select input recording mechanism ', wherein the first two and The keyword that system controls main table mark menu is identical, and when execution is according to keywords worth equal principle and calls；' Select input record Number ' it is to distinguish same menu forms, when different ' writing value field list ' is using different Select input methods, not using this method table Same record setting.

2. alternate key totally 2: editor's table class, editor and list serial number, mark hold that table that menu uses Row Select input.

3. the Select input method of literary name section executes parameter:

Parameter: ' writing value field list ', mark carry out Select input by method as defined in current record to those fields, can To be a field or field combination (the field name sequence separated with comma)；

Parameter: ' condition table class ' and ' calling Select input condition ' judges whether to execute Select input；It is held when condition is true Row does not execute for fictitious time.

4. filtering chosen candidate value tables of data records the parameter used:

3 kinds of filter methods are defined by parameters described below, the chosen candidate value tables of data record used for filtering Select input；

● chosen candidate value data table name；

● menu forms must record field list class in advance；Field must be recorded in advance；The corresponding chosen candidate value literary name of field must be recorded in advance Section；

● the public variable of filtering chosen candidate value tables of data record and corresponding chosen candidate value data sheet field name；

● chosen candidate value tables of data record filtering conditional expression；

Illustrate: wherein ' filtering ' and ' according to condition filtering by public variable ' and ' table record filtering method table ' design method phase Together；And use menu forms ' field must be recorded in advance ' and ' corresponding chosen candidate value literary name section ' value relation of equality is alternately worth simultaneously Table record filtering condition；

5. according to parameter: ' chosen candidate value field name ' and ' reading chosen candidate value mode ' determines the chosen candidate value of Select input；

Chosen candidate value mode is read using enumerating shape parameter: only one chosen candidate value of the alternative value field of 1 one records, 2 one The alternative value field of record has multiple chosen candidate values.

6. according to ' taking selective value mode ' parameter to determine the method for executing Select input: 1 chosen candidate value write-in of primary selection Edit field once selects multiple chosen candidate value write-in edit fields；

' selective value mode ' use is taken to enumerate shape parameter: 11 chosen candidate value of selection, the 2 multiple chosen candidate values of selection.

7. being determined after executing Select input, the other of execution write table handling according to following 3 class parameters:

● ' chosen candidate value table takes other value field list of file names ', ' editor's table correspondence writes value field list of file names '；

● ' field name that the decomposition value of selection result is written '；

● ' the table class for setting selection number ', ' setting selection number field name '；

It executing from the other field values of chosen candidate value table or by the decomposition value of selection result, table corresponding field is edited in write-in, and Set the write operation of selection number.

8. executing other regulations of Select input

● determine whether Select input executes password authentification according to ' password confirming ' parameter value；

● according to ' selective value repeats to judge that class ' parameter carries out selective value and repeats to judge, provides error message when repeating；

● whether determined according to ' whether allowing to edit ' parameter allows to carry out keypad editor typing when Select input；

● according to parameter: ' whether allowing to input new option when taking selective value mode=2 ', when determining Select input whether The additional chosen candidate value of keypad editor can be used.

Note: selective value repeats to judge that shape parameter is enumerated in class use: 0 is not, and 1 current form all records, and 2 tables of data are all remembered Record；Shape parameter is enumerated in other 3 parameter uses: 0 is not, and 1 is.

9. ' Select input method table ' editing interface is shown in Figure 10.

7, menu background process processing method table designs

Development platform handles the foreground process that menu widget packet should be realized, controls main table and system auxiliary control by system Table parameter definition is handled the background process that menu should be completed, by ' menu background process processing method table ' parameter definition.

The background process processing method of database application system menu is decomposed into newly-increased table record, modification table by development platform Record deletes table and records three classes tables of data WriteMode, and devises the execution parameter of each WriteMode, according to these when execution Dynamic state of parameters generates SQL statement, completes tables of data write operation, realizes the functional requirement of background process processing；For that cannot use The function that dynamic SQL statements are realized, by calling ' data base procedure ' code write to realize.

User service data table is divided into two major classes when design: value table and writing value table, value table is dynamic SQL statements Data source, referred to as ' meter reading '；Writing value table is the object table for executing write operation, referred to as ' writing table '；Value table and write value table can be with It is menu using table, may not be menu using table, the latter is referred to as ' new table '.

(1) major key totally 6: menu serial number, menu forms serial number, the Row control option of calling, calling function Button serial number, executes serial number at WriteMode；

They are described with integer, and wherein the first two and system control main table to identify the keyword of menu identical；

It is filtered when execution according to ' menu serial number ', ' menu forms serial number ', ' Row control option ', ' function button serial number ' Then this method table record is executed the record filtered out by ' executing serial number ' sequence；

' function button serial number ' correspondence system control the menu function button of main table enumerate serial number；

' Row control option ' correspondence system controls the option serial number of ' the Row control option list ' of main table；

WriteMode is divided into 6 kinds, using enumerating shape parameter: 0 judges whether to exit calling, 1 newly-increased record, 2 modification records, and 3 Deletion record, 4 have record modification, and no record is newly-increased, and 5 call data base procedure；

Be divided into 5 kinds to the method for field assignment: ' assign constant ', ' unconditionally assigning transition formula evaluation ', ' condition tax transition formula evaluation ', ' executing write operation for another specified data table as meter reading ', ' sql sentence assignment '；This 5 kinds of methods can use as needed It is one such or a variety of；

WriteMode is equal to 0, for judging whether current ' executing serial number ' later this method table record executes；

WriteMode is equal to 1, for increasing ' writing table ' record newly, firstly generates ' writing table ' record major key and customer service is closed Then key word gives other field assignment with 5 kinds of methods to field assignment；

WriteMode is equal to 2, for modifying ' writing table ' record, is determined first according to ' modification or deletion write operation execute method ' The record of modification operation is executed, then modifies field value with 5 kinds of methods to field assignment；

WriteMode is equal to 3, for deleting ' writing table ' record, is determined and is executed according to ' modification or deleting write operation execution method ' The record of delete operation, then delete ' writing table ' record；

WriteMode is equal to 4, first determines whether that ' writing table ' whether there is or not condition record is met, has and execute modification note when meeting condition record Record operation increases record operation newly without executing when meeting condition record；In this way, can not make to delete note when there is the condition that meets to record Record operation；

WriteMode is equal to 5, the write operation for dynamic s ql sentence cannot to be used to realize；When execution, ' the data write are called Library process ' realize write operation.

(2) user intervention whether ' background process calling ' executes

To have prevented user overdue ' background process call buttons ', but temporarily it is not necessary to perform the next step process processing Requirement, setting ' process call the prompt information ' parameter whether executed；When execution, if the function button serial number called is equal to 10, and the parameter value is not sky, then releases the prompt information, receives keyboard input, inputs Y, executes write operation, input N is exited Background process calls.

(3) when controlling option=99, ' Row control whole option modification field value is uniformly processed ' is executed, to reduce ' menu background process processing method table ' records and is convenient for parameter editor, unrelated with the execution parameter of 6 kinds of WriteModes, uses combination Parameter, format: [{ value class, table class, and list serial number, WriteMode, write value field name }, { Row control option list }, { process Option is corresponding writes value list for control }]；

Each write method for writing value field name is included with [], multiple to be separated with comma；

Use to enumerate shape parameter as follows: table class: ' table class ' parameter；WriteMode: 1 forms current record, 2 forms are all remembered Record；It is worth class: 0 constant, 4 public variables；

Note: when value class is public variable, corresponding public variable value is identified with the serial number of enumerating of public variable；

(4) ' meter reading ', ' writing table ' and the meter reading record that write operation uses record totally 6 parameters with table is write:

● meter reading class；Write table class；

● read record mode: 1 forms current record, 2 forms all record, and 3 is new by sublist, sublist whole record reading Result set uses, and 4 are all recorded using new result set；

Note: when forms only have, sublist is subordinated to main table or sublist is subordinated to the part record of sublist, but need to all from When belonging to record execution write operation, usage mode 3 or 4；

● meter reading and list serial number；Write table and list serial number；

● write new table name (writing data table name of the non-menu using table when)；

Note: meter reading class writes table class as ' table class ' parameter；Read record mode is to enumerate shape parameter；Two and list serial number Numeric parameter；Writing new table name is string argument.

(5) judge whether write operation as defined in a certain record of this method table executes and write operation executes number

', ' date terms of execution ' and the one ' write operation that uses the meter reading condition of two groups of conditional parameter ' execution executes time Number ' parameter definition；' write operation execution number ' is determined according to the meter reading condition of satisfaction ' execution ' record strip number when execution；

● the meter reading condition of execution: for conditional expression；It is unconditional to be defaulted as when sky；

● write operation executes number, to enumerate shape parameter: 0 it is each record it is each execute primary, 1 each to meet condition record each It executes once, records one more 2 and meet condition Exactly-once, recorded 3 more and all meets condition Exactly-once；

● the date terms of execution uses 4 parameters: date field table class, date field and list serial number, date field Name, date judgment mode；

Wherein ' date field table class ' is ' table class ' parameter；' date field and list serial number ' is integer

Shape parameter；' date field name ' is string argument；

' date judgment mode ' is to enumerate shape parameter: 1 monthly last day, 2 monthly first day, 3 quarterly last days, 4 quarterly first day, 5 last days every half a year, 6 first day every half a year, 7 annual last days, 8 annual first day, 9 Mondays, 10 Sundays；

● when WriteMode=0, it is unsatisfactory for the prompt information of execution condition, is string argument；

Note 1: ' WriteMode ' is equal to 0, currently executes whether the later method table record of serial number executes for judging；When discontented When foot ' the meter reading condition of execution ', the current later this method table of serial number that executes is not executed and records defined write operation, and is provided Do not allow the prompt information executed；Otherwise subsequent write operation is continued to execute；

Note 2: if ' WriteMode ' is not equal to 0, if being unsatisfactory for ' the meter reading condition of execution ', method table record rule are not executed Fixed write operation；Otherwise, write operation is executed by ' write operation execution number '；

Note 3: if ' WriteMode ' is not equal to 0, and meet ' the meter reading condition of execution ', but be unsatisfactory for ' date terms of execution ' When, write operation as defined in the method table record is not executed；

Note 4: ' date field table class ' does not judge date terms when being equal to 0.

(6) it modifies or deletes write operation and execute method, totally 5 parameters:

● it writes the modification of value table or the recording interval deleted and executes method: 1 forms current record, 2 forms or new table are whole 1*N endless form of one-to-one modification when record and read-write table are more records and equal record number, 3 meter readings are a certain What field saved writes table record xuhao record, M*N endless form when 4 read-write tables are more records, 5:for I=1TO N Endless form；

● writing table result set is reading and writing table associate field when more recording；

● meter reading saves modification or the field name of deletion record xuhao, only ' executes method 3 ' to use；

● deletion records the condition or new table record filtering condition that should meet with table is write when modification record；

● meter reading and literary name section comparison condition is write, uses two parameters:

1. conditional formats: 0 is unconditional, after section of writing before 1 reading field, 2 write read field before section after；

2. condition: it uses ' > ', ' < ', '=', ' in ' is used as comparison operator, ' meter reading ' and ' writing table ' field is connected, Composition condition comparison expression；

Note: shape parameter is enumerated in ' write the modification of value table or deletion record range and execute method ', ' conditional formats ' use；It ' reads Table saves modification or the field name of deletion record xuhao ' use integer sequence；Two conditional parameter use condition expression formulas；Its Its parameter uses character string or character string sequence；

Illustrate 1: ' forms current record ' and ' forms or new table all record ' executes writing for write operation for Explicit designation Table record；

Illustrate 2: the 1*N endless form of ' one-to-one modification ' has N item record for ' meter reading ' and ' writing table ', reads ' to read Table ' one record writes the corresponding record of ' writing table ' sequence；

Illustrate 3: ' a certain field of meter reading save write table record xuhao record ': for write ' writing table ' fixed one or Multiple xuhao records；

Illustrate 4: ' M*N endless form when read-write table is more records ': for sequentially executing ' meter reading ' whole M notes Record: reading ' meter reading ' one record, according to ' read-write table incidence relation ', ' meter reading and write literary name section comparison condition ' and ' writes table item Part ', judge each record in ' writing table ' N number of record, write operation is executed when condition meets；

Illustrate 5:for I=1TO N endless form: for by for endless form execution write operation, loop parameter fill in In ' meter reading and write literary name section comparison condition '；

Parameter format: the field name that cyclic variable uses recycles initial value, recycles final value, and circular increment is +/-；

Cyclic variable must be integer type field, and the field current record value, LAO_FIELD can be used (to compile for circulation initial value The field current record value before volume) or MIN (the tables of data field minimum value)；Recycling final value can be used MAX (tables of data word Section maximum value)；Circular increment is positive integer or negative integer；It is +/-: to be used for specified modification cyclic variable method.

(7) when WriteMode is newly-increased recording mode, a when write operation of every executions write the newly-increased record strip number of value table,

The major key of newly-increased record and the defined parameters of customer service keyword generation method:

● newly-increased recording mode: 1 every newly-increased record of write operation of execution；2 write operations of every execution according to point Solution value increases a plurality of record newly；

● write operation of every execution increases a plurality of record executive mode newly: 1 constant list is decomposed, and 2 value literary name sections are decomposed, 3 take a certain field value of a plurality of record of other tables using sql sentence；

● newly-increased record major key generating mode: 1 value table xuaho, 2 value table xuaho, xuaho1,3 value table xuaho, Xuaho1, xuhao2,4 value table max xuaho, 5 write value table max xuaho, and 6 operation logging xuhao, 0 currently writes value Sublist xuhao currently writes value sublist xuaho, xuaho1；

● newly-increased record write key number；(it is equal to 1, only writes xuaho, be equal to 2, write xuaho, xuaho1, be equal to 3, write xuaho、xuaho1、xuhao2)

● write key number is greater than the last one keyword assignment method when taking number: 0 sets 0；1 decomposes serial number；2 write son Table: maximum xuhao1；Write sublist: maximum xuhao2；

● the constant list of decomposition；

● ' meter reading ' takes decomposition value field name；

● ' writing table ' writes the field name of decomposition value；

● take the s ql sentence of ' meter reading ' multiple record values of field；

Note 1: what is used enumerates shape parameter: ' newly-increased recording mode ', ' newly-increased record major key generating mode ', ' write key Number is greater than the last one keyword assignment method when taking number ', ' increasing a plurality of record executive mode newly '；

Note 2: write key number, which is greater than, takes the keyword among when number to set 0；

Note 3:3 kind ' increasing a plurality of record executive mode newly ' can be used alone, and also can be used in combination, with one, two or three Position integer mark；Constant list decomposition or value literary name section are decomposed, the newly-increased record of a decomposition value；The newly-increased record of mode 3 Item number is identical as the table record strip number of ' sql sentence value condition ' is met；

(8) field assigns constant value, uses 2 parameters: ' assigning constant value field name sequence ', ' the constant value sequence of tax ', It is defined using character string sequence；

Note 1: character string constant is not added quotation marks and is included when character string includes comma with { }；

Note 2: date constant uses four kinds of fixed date formats:

YYYY；YYYY-MM；YYYY-MM-DD；YYYY-MM-DD hh:mm

Note 3: the constant value for assigning constant value field name and tax corresponds；

(9) ' type expression ' when field is using expression formula assignment, uses enumeration type parameter identification:

1 numerical expression, 2 character expressions, 3 statistics calculation expressions, 4 assign public variable value, and record takes a word more than 5 Segment value is connected with comma, and 6 meter readings are to literary name section copy is write, and 7 write table copies to meter reading field, and 8 date expression formulas record one more 9 A field take not repetition values connected with comma, 0 constant；

Note 1: when assigning public variable value, parameter value is identified with public variable serial number；

Note 2: it first according to the type expression calculation expression value of assignment when execution, then executes assignment or field value is copied Shellfish.

(10) unconditional multi-field expression formula assignment

Use 3 parameters: ' the expression formula class list of assignment ', ' writing value field list of file names ', ' assignment expression list '；

Note 1: expression formula class does not use 0: assigning constant；

Note 2: each expression formula is included with { }, multiple to be separated with comma；

Note 3: ' the expression formula class list of assignment ' is to enumerate argument sequence；' writing value field list of file names ' is character string sequence； Each assignment expression is one of above-mentioned ' type expression '；It is corresponded when assignment.

(11) condition multi-field expression formula assignment

Use 5 parameters: ' the expression formula class list of assignment ', ' condition list ', ' writes value field to rank ' condition class ' Table ', ' assignment expression list '；

Note 1: ' condition class ', using enumerating shape parameter: 1 meter reading field condition, 2 public variable conditions；' condition ' is condition Expression formula, public variable use the corresponding field name of management organization's table；Its excess-three parameter definition and ' unconditional multi-field expression Formula assignment ' it is identical；

Note 2: each condition write value field list of file names and conditional expression is included with { }, { } number is identical, correspond, It is multiple to be separated with comma；Each assignment expression is included with { }, and with assignment expression class and write value field name correspond.

(12) using another specified data table as ' meter reading ', referred to as ' meter reading 2 ' executes write operation and uses 5 parameters: ' meter reading class 2 ', ' read record mode 2 ', ' writing value field name ', ' list of assignment expression class ', ' assignment expression list '；

Note 1: ' meter reading class 2 ' is ' table class ' parameter；' read record mode 2 ' and 4. middle read record mode provide identical；Remaining Three parameter definitions are identical as ' unconditional multi-field expression formula assignment '；

Note 2: each assignment expression is included with { }, and is corresponded with ' assignment expression class ' and ' writing value field name '.

(13) sql sentence assignment uses combination parameter:: { the table class of additional xuhao condition }, { writing value field list of file names }, { sql sentence }, { value condition }, { sql sentence serial number }

Note 1: ' value condition ' is conditional expression；' sql sentence serial number ' is used to use when debugging；' additional xuhao condition Table class ' be it is specified using which tables of data of menu forms when taking ' meter reading ' current record, it is identical to define method with ' table class '.

Note 2: ' sql sentence ' is identical as database sql Sentence format；A plurality of sql sentence is separated with &&；

Note 3: ' sql sentence assignment ' parameter is defined with character string.

(14) data base procedure is called

Use combination parameter: { procedure name }, { the main literary name section list for passing to process } { pass to the sublist word of process Duan Liebiao }, { the sublist list of fields for passing to process }, { the source literary name section list for passing to process }, { public variable sequence Number, { sequence number parameter of calling }；

Note 1: ' sequence number parameter of calling ', which is used to distinguish multiple menus or ' the different records of same menu this method table ', to be made The call parameters of different disposal method when with same ' data base procedure '；

Note 2: in addition to ' procedure name ' parameter cannot be empty, remaining parameter is all in accordance with needing to be arranged；

Note 3: ' data base procedure ' parameter is called to be defined with character string.

(15) background process handles the prompt information parameter that is finished

' after maximum execution serial number ' write operation is finished, or controlling option and being equal to 99 when each control option<>99 After write operation is finished, the prompt information is provided；It with ' when WriteMode=0, do not allow prompt information ' public one executed A parameter.

(16) ' menu background process processing method table ' editing interface is shown in Fig. 7-Fig. 9.

8, menu operation priority assignation table designs

To the tables of data that menu uses, when different system login people logs in application system, to the operating right of menu By the control table parameter definition, there are six parameters altogether: menu serial number, class's station class, authority definition class, Responsibility of Staff or personnel compile Number, menu read right, menu write permission；

1. the parameter used:

● menu serial number: it is identical that main table menu serial number is controlled with system；

● class's station class: identical as table class of management organization station class；

● authority definition class, enumerate shape parameter: 1 is defined by Responsibility of Staff, and 2 are defined by person number；

● Responsibility of Staff or person number: Responsibility of Staff or person number's list using menu operation permission；

● menu read right, enumerate shape parameter: 0 nothing, 1 has；

● menu write permission, enumerate shape parameter: 0: nothing, 1 has；

2. menu operation permission uses ' menu operation permission configuration interface ' by the corresponding system function button of development platform Setting；

3. ' menu operation permission configuration interface ' is shown in Figure 12.

9, management Object table design

1. database application system management set and management step analysis:

● any management set for logging in people of database application system is divided into three categories: the set of object, the set of people, people with The set of object；

● the set of object: such as warehouse, substation, workshop, the goods and materials of storage or the equipment used；

● the set of people: such as teams and groups, department, warehouse, substation, workshop, the personnel having under its command；

● the set of people and object: such as warehouse, substation, workshop, the existing personnel having under its command, and there are goods and materials or the use of storage Equipment；

● management level is divided into two classes: ' vertical management level ' and ' intersecting management level '；

● ' management organization's table ' and ' personnel are used such as unit → department → teams and groups → personnel for vertical management level Table ', with unit name, department's name, teams and groups' name, personnel's name (person number), department number, teams and groups number mark management set；
