Detailed description of the invention
The present invention is described in detail for illustrated embodiment below in conjunction with the accompanying drawings.
The present invention is broadly divided into following step, first looks for realizing the various different scheme of goal systems, is solving
The data flowchart that the stage of reading demand analysis obtains is the basis imagining various possible schemes.Then available from these
Scheme in choose relatively reasonable scheme, then each scheme is designed a corresponding workflow diagram, according to
The system flow chart designed chooses out all of physical element.Should follow carrying out software structure design when
Main operational principle is each functional module Independence Principle, and module may diminish to model, controller, arrives greatly window, program
After Module Division completes, it is possible to start to devise.
The process of design is generally made up of two main stages: system designs, and determines the specific implementation of system；Knot
Structure designs, and determines software configuration.
System structure is as follows:
The full name of B/S pattern: Browser/Server Mode (Browser/Server).Owing to these of structure are not enough, in tradition
Structure in the middle of add last layer, the function that original client computer is responsible for is given intermediate layer and is realized, and this intermediate layer is clothes
Business device layer.So, client, with regard to not responsible original data access, need only install browser in client the most permissible.Former
Come server as database server, on database server installation data library management system and create data base.Clothes
Data base is conducted interviews by the effect of business device exactly, and passes to browser by work net.So, server is browser
Server, is again the browser of database server.
In such a mode, client computer just becomes a simple browser, defines " fat server/thin client "
Pattern, here it is browser server pattern.Structure based on browser server pattern will combine with data base, formation
Computation schema based on data base, and being applied to by this model, has ultimately formed three layers of client-server application structure, and three
The three of application system functional planes have been carried out clear and definite segmentation by Rotating fields so that it is logically the most independent.
Under three-layer architecture, represent that layer, Business Logic, data Layer are divided into three relatively independent unit.
Representing layer i.e. Web browser, comprise the display logic of system, it is positioned at client, is used for generating browsing client
The user interface of display in device.Its task is responsible for obtaining the data of user's typing, completes the verification to logging data, by
The Web browser a certain Web server on network proposes service request, after Web server carries out authentication to user
Send client request operational data to Business Logic by agreement, then ask the operating result of operation to be used by completing user
Grinding a few agreement and send client to, client computer accepts the homepage file transmitted, and its display on Web browser.
Business Logic includes one or more Component service, and they applied business rules realize application logic also
Complete the data required for application program runs to process.As a part for this process, intermediate layer is responsible for processing from data
Store or be sent to the data of data storage.Its task is to accept the request of user, performs corresponding extension application
Being attached with data base, propose data by Peer to database server and process application, application is processed by data base
After the result that data process is submitted to Web server, then sent back client by Web server.
Such three-layer architecture significantly reduces the pressure of client computer, the Web that distributes to of load balancing need not be taken
Business device.Owing to client computer has given server transaction process method part, it is no longer responsible for processing complicated calculations and data access
Deng Key Transactions, be only responsible for display part, thus attendant's no longer maintenance work for program hurry back and forth in each client computer it
Between, and main attention is placed on the renewal work of program on function server.This three-decker is the most separate,
The change of any one layer does not affect the function of other layer.
The overall traffic flow process of system: system manager by logging in, through verification for validated user laggard enter behind website
Platform, i.e. can operate the relevant information of job order；Warehouse keeper is by logging in；Through verifying as legal entrance website
After, can manually input and material is carried out unique tags；Handheld device end, in the flow process produced, by resolving two dimension
Code data also and in data base are compared and are determined whether to perform the function of filler.Need the main program module write and
Business process map is as shown in the figure.
The establishment of data dictionary: data dictionary is the set about data message, namely to comprising in data flow diagram
The set of all elements definition.Any is all to consult uncomprehending bar teleological interpretation, data word for the topmost purposes of people's dictionary
The effect of allusion quotation provides the description information about data to people the most just in software analysis and design process.Data flow diagram and data
Dictionary collectively forms the logical model of system, does not has data dictionary data flow diagram the not strictest, but does not has data flow diagram data
Dictionary also is difficult to play a role.Only data flow diagram and put data flow diagram precise definition together, just can collectively form and be
The specification of system.
Data dictionary be mainly used for the main tool as the molecule stage.One group tight one is set up in data dictionary
The definition caused contributes to improving the communication between analyst and client very much, therefore will eliminate the most possible misunderstanding.Data dictionary
The control information of each data element comprised is of great value.Because listing one given data element of use to own
Program, it is easy to estimate to change the impact that an element will produce, and all affected programs or module can be made phase
Should change.
Owing to temporarily also not having automatic data dictionary processing routine, card form is used to write data dictionary, every card
The information describing a data element is preserved on sheet.This way preferably achieves above-mentioned requirements, particularly updates and revises
Come easily, it is possible to the information of each data element of individual processing.The information comprised on every card has: name, another name, retouches
State, definition, position.
In system concept structure ER model, comprise " entity ", " contact " and " attribute " three bases.
1) entity: entity is the things that objective world exists and can mutually distinguish.It can be people can also be animal；
Can be concrete things can also be abstract conception.
2) contact: contact refers to each things contact to each other in objective world.Contact is divided three classes: man-to-man pass
System, the relation of one-to-many, the relation of multi-to-multi.
3) attribute: the character that attribute is entity or contact is had, a usual entity is portrayed with some attributes.People
Realistic problem is understood the most exactly by entity, contact and attribute these three concept, therefore, the thinking of ER model relatively people
Mode.Additionally, ER model uses simple graphical symbol to represent systems analyst's understanding to problem, it is unfamiliar with the people of computer
Will also understand that it, therefore, ER model can be as the media of communication between user and systems analyst.
One preferable system will be carried out at the initial stage of design and sufficiently analyze work, and will be according to certain order
This is completed, first should carry out data analysis work, design data base.Analytical database Construction Problems time
Wait, it should start with from demand analysis, all data that will use of the system that gets from demand analysis, and planned
Good, extraction entity and attribute thereof, set up model.It is the list entity such as operator, job order, user profile individually below, system
All data to be used, all will be expressed as follows with the form of E-R figure:
As: physical operation person and attribute E-R figure thereof；Job order and attribute E-R figure thereof；User profile and attribute E-R figure thereof.
System based on actual production procedure, main prominent job order is assigned, job order in detail, Quick Response Code generate,
The functions such as Modify password, this system is broadly divided into the big functions of modules of above-mentioned three.Assign module management person at job order can repair
The operation of pending job order such as change, job order can be increased newly, in the attribute of job order can be gone amendment etc. by manager
Hold.
The task of system logic structure is exactly that the ER of conception framework design stage design is schemed, and is converted into and selects DBMS institute
The logical structure that the data model supported is consistent.
System logic structure is as follows:
1. it is mainly, from E-R figure to the logical design in relation schema conversion data storehouse, the general relation that is converted into by conceptual model
Pattern, is namely converted into relation schema by the contact between the entity in E-R figure, entity attributes and entity.Transformed
In journey, following problems may be encountered:
1) Naming Problems.Naming Problems can use original name, it is also possible to names separately, it is to avoid bears the same name.
2) non-atomic attribute question.Non-atomic attribute question can be carried out longitudinal direction and be walked crosswise expansion.
3) contact transfer problem.Contact available relationship represents.
2. the optimization of data model, the result of DB logical design is not unique.In order to improve data base further
The performance of application system, also should the structure of suitably modified data model, improve the speed of inquiry.
3. relational view design, the design of relational view is also called the design of external schema, also makes user model design, and is to use
The data pattern that family can directly access.In same system, different user can have different relational views.Relational view is from logic
Pattern, but in structure with likely differ from logic model, so it is not the primary subset of logic model in form.
