Description
Technical field
The invention belongs to a kind of method based on P2P (peer-to-peer network) construction information system, acknowledgement messaging mechanism is provided, data structure and the data content of relevant information, response have been defined, proposed a kind of for data structure test automatically, modeling and autoranging, in particularly a kind of peer-to-peer network based on the distribution of comentropy, obtain, transmit, the logical difference construction system data integration method of collaborative and use.
Background technology
Electronic government affairs system generally rests in the office automation system in the office, on-line approval system, the more such contents combinations of portal website at present, but not the core content of E-Government obviously, the function of government is diversified, it is an organ of power, main task is decision-making and implementation and supervision, the assurance behavioural norm is coordinated, leader's action etc., this information that needs to have their own characteristics each on the information support of very numerous points in the society and these aspects distributes, this be a portal website can't bear.At present in China except that a few cities such as Beijing, Shanghai, the C/B/S Design Pattern is all pressed by this system, sets up large server in government centers, requires all departments that information is reported to this server process, some in addition require to lay optical cable again, reintegrate data.In fact, present province, city's one-level government and large-scale enterprises and institutions, all generally set up the mis system of oneself, data in these systems are constantly to change with mobile, if as top mode is rebuild a system that occupy the upper strata, do not give full play to the effect of local supplies, can not obtain local real time information, do not set up center and Local Activities yet, organically get in touch.If similar system is all so built, will produce waste greatly, cost is high, and can produce unnumbered data redundancy, basic unit's repeated acquisition data, repeats to import, and administrative department's information asymmetry is difficult to support localized administration.Have only the P2P of utilization technology to address the above problem preferably.Be different from basic P2P system as electronic government affairs system: communication object has hard objectives, particular content, upgrades in time; Assemble data from each local system or next stage system, physics can not have the layering off grade, has layering that grade is arranged but use; File has the different demands that initiatively provide, search for discovery; May be regularly mutual, also need to adapt to the burst requirement; Can batch process, also to prepare single-piece and reply; Data have before the destination needs combination, and what have needs dismounting, needs to solve logic isomery problem.Require that in class work such as office automation, workflow, permit business for example collaborative work is arranged, mutual function fast.Need up and down and coordinate and synchronous function, for example (for example city's level work is controlled by the city-level workflow to the superior and the subordinate's workflow, if work relates to or changes and distinguish one-level, become the work in district, connect the sound zone system workflow) etc. control information aspect problems such as transmission, forwarding, cooperation are arranged.Usually with generalized information system, exist with some complication systems such as post and telecommunications system and to maintain close ties with.Longitudinal systems such as government finance, tax revenue, education for example; Horizontal system will be distinguished pattern of wants overlay network between industry, and comment on network is staggered, and each node all may be got in touch with many networks.Data type is various, and these Data Sources, whereabouts are clear, and definite functions is divided carefullyyer, and structural difference is very big.When deal with data is shared, aspect isomery problems such as CPU, call duration time, file type, operating system, language are present settled problems, but the isomery problem of aspects such as data structure, data sense, data processing method, data content is highlighted, and must will solve the problem that function is integrated, data are integrated.Relate to the sharing problem that database and many binary files relate to more fine-grained internal data.Lay special stress on Information Security, integrality and consistency problem, concern concurrent operations problem etc.Need to consider the problem of long-range driving and distribution process, no matter be a system of adding or a plurality of system, the requirement of all must concern sending on the net, if another node requires to provide a certain data, if own node has, should manage to extract, be put into assigned address and take for the other side; If need own node move a certain preprepared program, information is handled and processed, should trigger relevant handling procedure processing and generate data and submit to required node.Come requirement should indicate the identity of oneself, demand reason or purposes (classification) indicate needed data content, structure, meaning, some content will be by pre-prepd normalized explaining; The node of receiving message will satisfy its call format as far as possible.The face behavior of coordinating all quarters concerned of an agreement must be arranged.
Therefore, will set up a high efficiency electronic government affairs system at present needs appropriateness to distribute on the one hand, (different with shared file system, node adds to withdraw from generally planning, and control is arranged, and the height of node autonomy), need effectively solve service scale and isomery, problem such as parallel, want the special concern safety issue, when specific design, also will consider the data integration problem, generally need control of layering central authorities and the architecture of building.
E-commerce system system based on the B/S pattern has had scale at present, generally is by businessman's distribution merchandise news, and the client finds condition of merchandise and each side address information by the search to distributed intelligence, finishes reciprocal process by online transaction again.Large-scale e-commerce system serves as main the support with the management information system of businessman self, based on server, database and web technology.The user object no fixed address can spread all over the world.Here do not reflect the such reality in objective world: in actual society, everybody is the consumer, also all is businessman, all needs to push the product of oneself to the world.Obviously present B/S pattern can't satisfy such needs, and the thought of P2P is on the contrary coincide with it.Need the mode that commercial matters information is provided simply, conveniently, easily, need the means that simply, reliably, accurately obtain merchandise news, need the bargaining environment of fairgroundization, need the diversified means of payment, need comprise the diversified mode of doing business that exchange of goods is such.These have proposed high requirement for the P2P system, need the way to manage and the policy standard in large-scale e-commerce system and online fairground, comprise information storage place, information distribution standard, relevant inspection method, corresponding finance and taxation policy, Trading Policy problem etc.Say that technically some is and the shared file system similar problem, as whether needing overlay network, the formation of overlay network, the means of maintenance, search and data mining on the net, solution isomery problem, safety issue or the like.But some requirement is higher, for example solves the isomery problem that the isomery problem is not only file, processing, environment etc., in addition the isomery problem of the meaning of data, expression etc.Requirement about fail safe is higher.Also more emphasize data integrity and consistency problem, concurrent operations problem etc. in addition.
Along with the continuous expansion of scope of the enterprise, the IT continuous advancement in technology, management information system has constantly been enriched by many enterprises, ERP system, the OA system, crm system, and many systems get up according to the different development of demand in the different phase of enterprise development.For these different systems, if want to use the data of other system, usually to from a system, print data, adopt the mode of manual entry to be entered in another system again.What we need do is to make up a general service platform, make on it any one system can both with the other system sharing data resources, if required data are deposited in other system on the one hand, just need provide a kind of general middleware to realize transmitting automatically, the data of having deposited in the other system are sent in the system that needs data, thereby avoid the collaborative work that manual typing realizes two systems, further optimize total system on this basis, reach the target of integrating between system, the maximum effect that performance is whole.This general service platform primarily will solve is integration problem between any two autonomous systems.
In sum, if the P2P network application is again to decision system, ecommerce, E-Government, the development of information processing aspects such as large multimedia application, no matter from fail safe, efficient, operation and design aspect, still the history from real application systems constitutes and which angle consideration of application need, network all must be tight structurized, it is contemplated that, needs to server in system will not be only one, simply layering is simple like that, consider to have in logic the server of difference in functionality: system is safeguarded, catalogue and route are provided, the management of equity point, to object indexing, act on behalf of purpose or need provide buffer memory for shunting for reaching ... or the like, consider again the needs of reliability to prevent that certain server from hindering for some reason, shutdown, withdrawing from etc. influences system stability, also to consider backup of server and some facility or redundant problem, must study the problem that need provide different configurations to different application.

Embodiment
The invention will be further described below in conjunction with drawings and Examples, but this embodiment should not be construed as limitation of the present invention.
System configuration of the present invention as shown in Figure 1.
Main message structure by maintenance device transmission requirement message in the third step of the present invention comprises: message name, the overlay network title that definition is relevant, definition message is delivered to the mode of destination, generate the equity point GUID of message, the equity point GUID of pass-along message, receive the equity point GUID of message, time-to-live (optional), the peer list of process (optional), host name, host address, user's name, password, required file name, the file storing directory, revise type, Date Required, database-name, the tables of data title, key (seeing Table 1); Main message also comprises message sublist file, and its message sublist file domain name structure comprises: field name, data type, keyword sign, relevant table name, foreign key sign, dictionary table title, interface parameters file name (seeing Table 2).
Wherein " host name, host address, user's name, password, required file name, file storing directory " refers to that the other side's response document mails to the destination related parameter is arranged." modification type " comprising: interpolation, covering, modification, interpolation+modification, deletion, inquiry etc." interpolation " mode refers to add the new data of sending here at tail of file." covering " refers to that the deletion legacy data is inserted the new data of sending here more hereof earlier." modification " refers to the new data sent here is analyzed its keyword earlier, and when the record that has keyword to conform in the current table of another system, data based keyword upgrades data in another system data table in the file with transmitting." interpolation+modification " mode requires to derive with preserving in the file finished the data that import to the current time from last time, when current table does not have record that keyword conforms to, import to data in this document in the tables of data fully; When the record that has keyword to conform in the current table, upgrade data in this system data table with data based keyword in this document.
If stipulated key in the message, should decipher importing more earlier.
If made keyword sign or inserted relevant table name and made the foreign key sign, require when importing data put into effect body integrity checking or referential integrity checking.
The structure of interface parameters table comprises in the present invention's the 4th step: component names, menu item names, the tables of data title, selected character segment number table is selected button number table for use, select list box field number table for use, last secondary table title, upper level table name claim, contact field 1, contact field 2, dictionary table title (seeing Table 3); The structure of dictionary table comprises: system's 1 title, system's 1 table name, table 1 field name, system's 2 titles, system's 2 table names, table 2 field name, meaning, maximum, minimum value, limit value value collection, constraints expression formula, whether allow repetition values, whether need code conversion, code table title, combinatorial formula, conversion program title (seeing Table 4).
Considering that data in the derived table may be the partial datas in the importing table, also may be partial data in a plurality of tables.Design general communication interface, just must finish importing, export reconfiguration, this conversion program wants to adapt to the needs of any system.This work designs general translation program again and finishes derivation, imports the file structure conversion by a dictionary table.Consider real data imperfection (a common system derives the partial data that just imports table one record with the data of a record of file), be defined in the dictionary table and filled in " table 1 field name ", but do not fill in " table 2 field name ", remove this data correlative during conversion.In dictionary table, filled in " table 2 field name ", but do not filled in " table 1 field name ", allowed the null value of using instead of null value to fill its data during conversion, otherwise filled with space or 0 according to data type.If inserted contents such as maximum, minimum value, affiliated value collection, constraints, require when importing, data to be done the domain integrity inspection.Wherein " constraints expression formula " adds relation character with field name and adds the expression formula formation.Agreement has a special constraints expression formula: with " c " " " the expression value only is made of character A-Z $, or " c " " " the expression value only is made of numeral, decimal point, sign 0-9 $, special method is arranged in the conversion program, when finding this class constraints, call special method and test.If inserted the code table title, require when importing, data to be pressed the conversion of code table content.
The management information system mass data adopts coded representation, perhaps utilize code to add up, if when integrating, can require to adopt unified code system to integrate easily naturally, but under many circumstances, this requires not possess operability, therefore requires interface routine to solve the code conversion problem.Need one " code conversion table " of design, structure is: (system's 1 title, system's 1 code, system's 1 code content, system's 2 titles, system's 2 codes, system's 2 code content).Wherein code content refers to the meaning of yard representative, for example use the other mobile X-ray machine of a bed of code " X20020101 " expression: " 100KHZ type 30KW power Compact mobile X-ray machine ", in the future in " system's 1 code " hurdle, fill out " X20020101 ", in " system's 1 code content " hurdle, fill out " 100KHZ type 30KW power Compact mobile X-ray machine ", code and the title of identical product in second system of then filling out same model specification in system's 2 codes and system's 2 code content.
In interface routine, should see in the field that " whether needs code conversion " in the dictionary table whether be masked as "Yes" earlier, be, just check " code conversion table ", utilize this table to realize the conversion of two code datas if be masked as.When conversion, the data of importing may be the combinations of a plurality of importing data, perhaps are the part of its composition.If this combination or decompose and can calculate realization with a formula need write computing formula in dictionary table, when conversion, by formula make up or decompose.This computing formula is formed by connecting through connector by some fields of data derivation side.In the conversion program special method should be arranged, when finding this class computing formula, import again after calling special method and handling.If can not need design non-standard component program in addition with simple formulate transformation rule, in " conversion program title ", insert this program name, the general parts that import and export will call this program and finish conversion process.
Above designed system program structure as shown in Figure 2.
This system takes the end to end communication mode, comprises as lower member:
1. data conversion program: its function is to read the data file of each derivation, according to the dictionary table of message table and each group conversion foundation data is recombinated, and generates the file that imports for another system, and is dealt into the indication position.Message table vectoring information conversion program is done all and is imported and exported operation.
2. tables of data, dictionary table, code table and message table in the collecting and distributing device of data are safeguarded the universal component of (typing, modification, deletion, inquiry).
Finish be designed for concrete system before, need do following work:
1. determine the data structure of two number formulary certificates, determine the content of required the other side's data.
2. simulate new system data situation, the operation auto-analyzer procedure is both sides' data structure relatively, fills in dictionary table automatically.
3. study original system fail safe and integrality requirement, revise the dictionary table content.
4. determine code system, fill in code conversion table.
5. specified data sends and importing opportunity and control mode thereof, fills in the data registration form.
Derived data format conversion program flow diagram imports data format conversion program flow chart as shown in Figure 4 as shown in Figure 3.
Use above-mentioned parts to need to set up " interface parameters table ", its structure is: (component names, menu item names, the tables of data title, selected character segment number table is selected button number table for use, selects list box field number table for use, last secondary table title, the upper level table name claims, contact field 1, contact field 2, the dictionary table title, menu bar number)
Each line data correspondence is once called, an actual module that is equivalent to General System.
The meaning of each interface parameters:
1. " menu item names ": system's basis " calling interface parameter list " generates the next stage menu of Control-Menu, each " menu item names " corresponding menu item, and inserting content in " menu item names " is the label of this menu item.
2. specifically insert in every row " component names " the one's own profession menu item when selected desire the title of the parts that call and carry out.To use following 6 parts among the design: unirecord data maintenance parts, layering multilist data maintenance parts, the table formateed data apparatus of repair parts, wall scroll spare inquiry parts, the query composition parts, the XML file imports parts.
3. the operation that all will specifically implement certain table in the database of at every turn calling of parts (is added data, is revised data, data query ... Deng, fill out the name of this time database of desire operation when calling and the name of table in " database-name, tables of data title ".
4. when revising data or carrying out deletion action, need to search data according to " keyword "." keyword " hurdle is used to fill out the keyword of operated table, if be made up of a plurality of fields, will use CSV to each other.
Can set up the interface according to selected field Automatic Typesetting when 5. parts call at every turn, " selected character segment number table " can insert the arrangement sequence number of the field of institute's desire selection with deciding view in this hurdle, use CSV between sequence number.Use field number and do not use field name, can strengthen data independence.
6. for reducing component files quantity, also be convenient to carry out function combinations, a plurality of functions that each parts is all integrated, each button is just represented a function, can realize different application by " selecting button number table for use " parameters selection button.
7. be handled easily or in order to standardize input, some data demand clicks by mouse and finishes, this can use the list box assembly to carry out." select list box field number table for use " and be used to represent that the input of those fields requires to adopt the drop-down list box operation.
8. " layering multilist data maintenance parts " can be at a plurality of tables of data operations with " query composition parts ".The name of filling in other table except that code table in " go up the secondary table title, the upper level table name claims, contact field 1, contact field 2 ", they are connected by contact field with master meter." layering multilist data maintenance parts " employing " tree " control selects to go up the table of secondary, for example, if with parts or the part one-level of administration extensions to product, can represent sales order number with the root of tree, represent product code in the order body with the second level, the third level is represented the parts or the part of a product, when selecting certain parts or part, the view of these parts or part is listed with unirecord interface form in the right, the operation of convenient data to these parts or part.Corresponding this application requires to fill in sales order data table name in " going up the secondary table title " hurdle, fills out sales order sublist data table name in " the upper level table name claims ", fills out the name of table of the data of storage means or part in " tables of data title "." contact field 1 " fills out the field name of contact between " going up secondary table " and " the upper level table ", and " contact field 2 " fills out the field name of contact between " upper level table " and " tables of data ".
9. " menu bar number " inserts the row number of the menu item of one's own profession correspondence.
The content of some data label need be done the variation (for example determining the Chinese label content according to English field name) of title, some field need be got in touch certain code table and be finished input or carry out data conversion, also some field will be carried out data integrity control when input, can be by " dictionary table " definition foregoing." dictionary table " structure is: field name, tag name, code table name, code table code field name, code table content field name (above two names must have one identical with some field names in the tables of data), maximum, minimum value, limit value value collection, constraints expression formula, computing formula.
Having some data in the data in actual applications is derived datas, and its value generates and only supply to show automatically when operation." computing formula " hurdle in the dictionary table is used to fill in the data value that calculates derived data, and its formula is made of the field name AND operator.Such design is arranged: when the data of certain field change in formula, all can by formula once calculate automatically, and upgrade the data of the field of filling in " field name " in the record of this formula of registration in the dictionary table with result of calculation in the part programs.If do not fill in " computing formula " data, program will not done this operation.In dictionary table, can also list in the control of some field is represented etc. that about physical dimension control, Position Control, color or voice related parameter is arranged.
When carrying out data maintenance and data importing and derive, the normal requirement provides data security protecting or provides different views to different user, for example for the certain user can only make query manipulation, the certain user can do the typing operation ... Deng; To stipulate not allow content of seeing some field etc. to the certain user., foregoing is concentrated in together, the structure of design interface parameter list is for this reason: user's famous-brand clock, operating right, hidden field famous-brand clock.Wherein, every row can be filled in a plurality of users' title in user's famous-brand clock, uses CSV to each other.Fill out i in the operating right, u, d, s represents interpolation, modification, deletion, search access right respectively, can be wherein a certain authority, also can be the combination of a plurality of authorities.Fill out the title of the field that will not represent this group user in the hidden field famous-brand clock, a plurality of field names can be filled in by delegation, use CSV to each other.Requiring all data maintenances and data importing to derive parts needs specification interface parameter list title before calling, if do not insert title, expression is worked as inferior calling and do not needed to do above control.
