[0005] In order to achieve the above-mentioned purpose of the invention, the inventive idea of the present invention is: based on the current main solution for removing the "chimney" of each business system and realizing cross-domain data sharing, a data center will be established, and there is a data center that is vulnerable to attacks and data tamper-proof capabilities Inadequate and difficult multi-source data integration, etc., a design idea and design model based on decentralization is proposed, and each business system determines and shares its own local data subject information according to the requirements of the data subject catalog. On this basis, each business system Construct, use and maintain a consistent network-wide data subject directory to achieve decentralized cross-domain data sharing

Embodiment 1
[0042] This embodiment provides three business systems (business system 1, business system 2, and business system 3) in the same business network to realize cross-domain data sharing through a cross-domain data sharing method based on data topics proposed by the present invention. A data subject-based cross-domain data sharing system constructed according to the present invention is completely deployed in three business systems. A cross-domain data sharing system based on data topics constructed by the present invention includes a data topic directory operation and maintenance module (1), a data transmission module (2), a data topic publishing module (3), a data parsing module (4), a data Subject directory fusion module (5), fusion verification judgment module (6), data subject access module (7), data subject response module (8), and data subject monitoring module (9).
[0043] Each business system puts forward the requirements of the system for data topics, and the business n...

The invention belongs to the technical field of data sharing, and particularly relates to a cross-domain data sharing method. According to the technical scheme, the cross-domain data sharing method based on the data theme is characterized in that a design idea and a design mode based on decentration are provided; the method comprises the following steps of: determining and sharing own local data theme information for each service system of the same service network according to a data theme directory demand, forming a whole network data theme directory which comprises a data theme, a data name, a data format and a data address, and independently operating and maintaining the whole network data theme directory; and querying the whole network data theme catalog to obtain the data address of the service system corresponding to the required data, and obtaining the theme data of the corresponding service system through the data address. According to the method, the robustness and the agility of cross-domain data sharing of the multi-service system can be improved by adopting a decentration mode, and the data tamper-proofing capability is enhanced.
Description
technical field [0001] The invention belongs to the technical field of data sharing, and in particular relates to a cross-domain data sharing method. Background technique [0002] In the field of military information, due to different business directions and different user groups, there are multiple independent business systems, which make it difficult to share data, resulting in the phenomenon of "chimneyization". With the advancement of military digitalization and the digital integration of various business systems , and for the military purpose of future multi-domain joint operations, it is necessary to realize cross-domain data sharing between different business systems. Current limitations are: [0003] At present, it is mainly through the construction of data centers to collect, aggregate, and integrate data from various business systems to achieve cross-domain data sharing of multi-service systems, thus breaking the phenomenon of "chimney"; the construction, use and ...
