The Research And Application Of Complex And Related Compare Method Based On The Different Constructional Data

Because of historical reasons, departments and trades have reserved enormous data, which is cannot be shared and exchanged automatically because some construction differences inside of system construction, operation system, database, and data construction. The data exchange of outside is artificially. The information society is coming, especially the flourish of internet technology, these data is urgent to be shared, exchanged, integrated and reused. The data integration of different departments is needed.Upon this social circumstances, in order to make disperse and different constructional data departments integrated and become to a whole one. This issue has a deep research on the compilation of different constructional data. And the study is applied for the program of"Liaoning Credit Data Exchange Center".Firstly, the article presents the source, research purpose, and the meaning of the issue as well as the current study situation in home and in abroad, and the technology development trend. Secondly, the issue makes an analysis and has researched arithmetic of character relevancy compared with string sequence and find out an effective way to make data related successfully. Then according to the program requirements it established the model to resolve the different constructional data relevancy. Finally, the issue according to the actually program circumstances to make up the model of different constructional data complex relevancy, also it expatiates the concrete measures to realize this model.
