Summary of the invention:
1 basic skills
Based on grid platform, on the isomeric data file management system (as PDM) of each enterprise, set up the shared data file management system.This system is based upon on the ORICAL Basis of Database, is made up of jointly the shared data bank of each enterprise, and the function that provides by grid platform forms unified data directory, is convenient to user inquiring.All databases storage files of this system all adopt 72 unified codings, by the mutual conversion of data dictionary foundation with enterprise's types of applications coded system, thereby, the unification and the single data source of realization data.This system partly is made up of grid platform, distributed data file management system, Unified coding rule, data directory, data dictionary etc.
1.1 the data file management system of data grids
Data management system is actually the file system of a distributed storage, develops on the ORICAL data base management system (DBMS).He mainly manages with document form information such as the digitizing drawing of enterprise, document, digitizing computation model, various source programs.Its management function comprises: mandate, safety management, access information, Version Control, State Control, set up between the file and concern, functions such as configuration management can be provided product documentation.Each enterprise utilizes this system to set up a shared data bank, the shared data file that enterprise is offered other affiliate this database of packing into.Comprising various PDM data messages.
The basic skills of its information stores and architecture are shown in Fig. 2,3.
According to uniform rules, distributed data base is managed by the local data keeper.Realize the unification of data by grid platform.According to the system authorization scope, by grid system, the user can utilize data directory check, download be distributed in each enterprise the shared data file.
1.2 realize single data source based on unified digital coding
At present domestic very many to the class coding, only aviation enterprise just adopts the nearly coded system more than 50 kinds.Comprising: document No. system, drawing coded system, information document coded system, software and model based coding system.Coding has the national standard codes system again, national military standard coded system, navigation mark coded system, enterprise's mark coded system, each enterprise of states such as the France of international co-operation model, Italy, the U.S., Russia, the coded system of each model specific.The difference in length of these codings is very big, and the longest 35, the shortest has only 7.The information that wherein comprises also difference is very big.How the shared data file to be carried out unified management, and guarantee that single data source becomes the key of system development by these codings.
For this reason, all kinds of information encoded attributes that project has at first comprehensively adopted, definition by induction can cover 72 Unified coding of all kinds of codings, this coding has very big extendability, for new coding definition leaves enough spaces.72 codings can be described 16 attributes of coding and form by being preamble code, status code and attribute code.According to topology relationship, can set up the mapping relations of the present and following various codings.
For the storing data files of whole virtual enterprise shared data file, all adopt 72 codings at enterprise's shared data bank.No matter company numbering is how like this, before entering shared data bank, all convert them to 72 codings according to corresponding relation, simultaneously the uniqueness of its coding is checked, to guarantee single data source.
For user side, still show the coding that original enterprise uses.Support data directory, code conversion and data dictionary and the administrative mechanism of single data source, see Fig. 3.
1.3 data directory
Be assurance user's the inquiry and the unification of data, the data file shared system has been set up the unified file directory of the shared data bank that comprises that all are distributed in each enterprise.This catalogue comprises the data file content of all distributed store, and realizes upgrading timely by grid platform.Unified catalogue is to exist with 72 coding forms in database, guarantees that the data of storing repeated code can not occur, through the conversion of data dictionary, then uses coding form with enterprise at user side and shows, is convenient to the user to identification.
In the data file shared system based on grid platform, according to authority, all enterprise customers can see and inquire about the unified catalogue on the shared data file system, and extract corresponding information by this directory and authority.
Owing to this catalogue is that grid system guarantees the timely and synchronous renewal of catalogue by " agency of each enterprise " along with the increase and decrease of the information of each enterprise's shared data bank changes.Guarantee that the catalogue in face of the user is in last state forever.Virtual enterprise member's data sharing mechanism as shown in Figure 4.
1.4 data dictionary
Data dictionary is the transformation rule between the coding rule, conversion corresponding relation between the various coding rules of enterprise's use soon and 72 coding rules of definition, by corresponding data dictionary software, realize that 72 bit code shapes and user oriented enterprise use the automatic conversion between coding.
On the other hand, when into the data file shared system is packed new file by each enterprise, data base administrator's local shared data bank of just the newly-increased coded file of enterprise being packed into, translate into 72 bit codes through data dictionary, and the uniqueness of inquiring about this new coding by data directory, the shared data bank of packing into after affirmation, unified catalogue is also upgraded thereupon.
When enterprise need adopt new coded system, data dictionary need upgrade, and promptly increased the transformational relation between new coding rule and 72 coding rules, and all dictionaries of data file shared system also will upgrade simultaneously simultaneously.This renewal work will be realized by " agency of each enterprise " of grid system upgrading automatically.For the renewal of the data dictionary of data file shared system, be that the dictionary management person by system implements and issue.Guarantee unifying and upgrading in time of data dictionary like this.
1.5 user interface
Set up user interface clearly with form web page.The user can finish the inquiry of strange land information and call from the interface.Also set up corresponding user interfaces for data base administrator and data dictionary management person.
The user can be by inquiry and the application of interface realization to whole shared data library file.
Strict control guarantees safety
For guaranteeing the safe and reliable of data file shared system, system has set up strict administrative mechanism.In data management, the operating right mandate is arranged, watch mechanism such as scope mandate.In management, each enterprise's regulation has only the data base administrator to have authority to increase and decrease information to shared data bank, the authority that other user only watches and uses.For the renewal of data dictionary, all data shared file system has only renewal and the upgrading by data dictionary management person's implementation data dictionary.
Be the safety that guarantees thanks, system also need set up corresponding authentification of user and security mechanism.
2 main rules
2.1 major function
This method can realize the following function of data sharing:
● the shared data file of enterprise will be stored in respectively in the shared data bank of enterprise separately, is in charge of by the data base administrator of locality.The data of native system will be with the form storage of data file, i.e. forms such as data pattern file, document, CAD drawing and source program.In local database, will all adopt 72 Unified coding.
● possess the function of data dictionary, when data file was packed into or take out, the coding of the shared information of the data file that will pack into by data dictionary was changed, and realized the automatic conversion between company numbering and the Unified coding.
● can store and inquire about all kinds of codings.User's total system data of database file directory can be provided, and this catalogue adopts company numbering in face of the user, be convenient to user inquiring.The data directory of storing in database simultaneously all adopts 72 codings.
● have the audit function of single data source.

2.4 72 Unified coding
2.4.1 set up the foundation of information coding mode
Under the information management system situation of Distributed Storage, setting up Unified coding is one of gordian technique that solves uniform data and single data source.Unified coding should be able to cover the coding rule of standard GB, industry standard such as HB, GJB GJB and company standard coding etc. hundreds of (only the relevant coding standard of aviation use reaches 50 kinds).The coding standard of countries in the world can reach hundreds of.For realizing the unified management of all kinds of encoded data files in database, need to set up the Unified coding that can cover all hundreds of coding standards.Its target is:
● being based upon in " virtual enterprise " grid system is the coded system that all enterprises can carry out unified management to information.
● realize both having kept the application of the familiar coded system of enterprise, simultaneously, after the encoded conversion, Unified coding can cover all traditional coded systems.Newly-established unified coding system has expandability, when running into new standard code, can define transformational relation smoothly.
● unified coding system should adopt holder to pounce on contextual definition, makes it concise and be convenient to use.
● unified coding system has increased the information such as sign of product degree of ripeness, adapts to the demand of user in the research and development of products process.
In GB, navigation mark and national military standard, there are some standards that the drawing file of various ways has been stipulated method for numbering serial and requirement etc., group's level coded system that these files are unified for we work out provides foundation.Title and their general requirements of several standards in table 2.1,2.2, have been listed to encoding.Also with reference to the coding standard of aircraft, the existing use of engine, gather through conclusion simultaneously, we have proposed group's level information Unified coding technical scheme.This scheme can cover the content of the various standards of having collected.

2.4.3.1 version number and status code
Some file, drawing will be indicated different versions, and some drawing or product will be indicated different degree of ripeness with status code.
Version number or status code can utilize the standby code (sign indicating number arbitrarily) of the 7th field to represent.Version number takies 4, generally represents with numeric string; Status code takies two bit codes to be represented, specifically sees the example of Fig. 6 and table 2-16,2-17,2-18.
2.4.3.2 suggestion about version number's coding
The Production Version coding accounts for 4 of status code, must not surpass.Wherein can add period.
2.4.3.3 identify about degree of ripeness
The definition of product degree of ripeness is as the criterion with the constituent parts definition, and this advises immature for reference.But the expression length of degree of ripeness is necessary for 2.
Actual conditions according to the aeronautical product development are divided into the description of aircraft type and product two class degree of ripeness, and provide the degree of ripeness description definition in each stage.
Also provide the definition of corresponding degree of ripeness sign indicating number in the degree of ripeness in each product development stage for drawing.Because it is country and industry still do not have this class standard, thereby propose reference scheme, for reference.。
For describing the drawing degree of ripeness in each stage, the integrated encode definition list 8 of various states is proposed, as the sign of product in status code or model degree of ripeness.

2.5 data directory
Data directory is the inventory of the All Files of whole data file shared system, is all lists that are distributed in the shared data bank of each unit (enterprise) are concentrated in the catalogue, forms the data directory of whole data file shared system.This catalogue is to depend on digital coding.In data directory, identical digital coding must not be arranged, to guarantee single data source.
Every data in the data directory are to adopt 72 Unified coding in database, are convenient to like this check whether initiate data file repeats with original data file, prevents that the data file of repetition or non-single data source from existing.Before each keeper was input to the new data file in the database, system checked with 72 coded data catalogues at first automatically, as finding that having existed same-code, system will refuse this data file automatically packs into.When new data was packed into, the relation between the data file that also needs to set up and deposited in was convenient to set up the associated data files change mechanism of notice mutually.
For ease of using, in face of the user, adopt the coding form of original undertaking.In the coded query process, the file class sign indicating number that utilizes preamble code to provide, the function that provides key words such as organization unit's code and applied code code to inquire about are provided in system.The user can also utilize condition such as the model, parts, version of file applications that the file of unified catalogue is inquired about and retrieved.
Data directory and Database Systems provide the function of retrieval jointly for the user, realize the following operation to file, as functions such as downloading, browse.
Conversion between 72 coded data catalogues and the traditional data directory is to finish by data dictionary.
2.6 data dictionary
Data dictionary is that this rule of transformation rule of encoded data file is determined according to the rule of this paper " 2.3 72 Unified coding " part definition.This rule definition the logic corresponding relation of 72 various codings of Unified coding and enterprise, each encoded content of having guaranteed enterprise can both have corresponding position in 72 Unified coding, realized both uniqueness conversions.
Data dictionary can be realized the bi-directional conversion of 72 various codings of Unified coding and enterprise, and the data directory that is about to corporate code converts 72 Unified coding load data base data directories to by data dictionary; Also 72 Unified coding data directories in the database can be converted to the various coded data catalogues of enterprise and be shown to the user.Each file is packed into or when downloading, also will be finished conversion operations by data dictionary.See Fig. 4.
Because the data dictionary of definition relation only is seldom a part of enterprise and the model coding that aviation enterprise uses at present, for whole industry and the other industry of using from now on, also need further definition of data dictionary transformation rule in the use, constantly enlarge the data dictionary content.The data dictionary definition should be defined according to unified logical relation, guarantees the unification of conversion.
Data dictionary will be safeguarded by the data base administrator of total system.After having defined new data dictionary rule, data dictionary will be upgraded, and data dictionary management person should be distributed to it all users rapidly.System will provide good user interface and to the maintenance function of data dictionary for the data base administrator.
2.7 synchronization mechanism
Data dictionary and data directory in use often need upgrading, need be distributed to all users by synchronization mechanism.System can upgrade data directory and data dictionary timely, makes the user use the state of sunrise all the time, to keep the single data source of system.
Synchronization mechanism can be realized by synchronizing function and the agency mechanism that grid platform provides.The part synchronization mechanism also can be realized by the network function of ORICAL database.
This method has realized software development and application verification, has proved that the method correctness is feasible.
