Embodiment Construction

[0024] The present invention will be further described below in conjunction with the accompanying drawings.

[0025] A cross-domain shared data model construction method, such as figure 1 As shown, it includes four stages: Step 1, build a data model warehouse based on the general data model, domain data model and coding table; Step 2, build a subset model of the data model warehouse, and extend the subset model to build information Exchange model; step 3, establish the mapping relationship between the information exchange model and the data entities of the shared data publisher and user; step 4, establish an information exchange package based on the mapping relationship, and the user extracts the shared data information according to the mapping relationship. The above process realizes the unified understanding of the semantics of the shared data by the publisher and the user, reduces the cost of using the shared data; and implements a set of mapping methods between the informa...

Abstract

The invention relates to the technical field of data sharing, and discloses a method for constructing a cross-domain sharing data model. Including the following process: build a data model warehouse based on the general data model, domain data model and coding table; build a subset model of the data model warehouse, and extend the subset model to build an information exchange model; establish an information exchange model and share data The mapping relationship between the data entities of the publisher and the user; the information exchange package is established based on the mapping relationship, and the user extracts the shared data information according to the mapping relationship. The technical solution of the present invention realizes a unified understanding of the semantics of exchanged information by multiple publishers and multiple users, effectively reducing the cost of communication and understanding of shared information between the information provider and the demander; simplifying the processing and use costs of shared data ; Reduced dependence on shared exchange platforms, supporting docking with various information exchange platforms.

Description

technical field [0001] The invention relates to the technical field of data sharing, in particular to a method for constructing a cross-domain shared data model. Background technique [0002] At present, government affairs data sharing is usually in which the publisher directly publishes shared information such as business database tables and files through the sharing and exchange platform, and then the user subscribes for use. However, this method lacks a unified definition of shared data semantics between publishers and consumers, and there are data format conversion problems between multiple publishers and consumers. To use the shared data, the user needs to do a lot of work, and the efficiency of data sharing is low. [0003] Therefore, the traditional method of sharing data is costly and difficult to use, and it is difficult to widely promote and utilize shared data. Contents of the invention [0004] The technical problem to be solved by the present invention is to...
