Application Research On Social Insurance Information System Based On Data Integration Of Grid

Each department chooses different software and hardware according to specific application in the current information system construction process of E-government. Data organized and managed to go on functionally to each separate department which when formed the data resources go into various"Isolated Islands". More and more applications and decisions require overall high-efficient visits to various kinds of data resources. In order to eliminate the information of the"isolated islands", we must integrate the legacy system. It is under this circumstance that the Data Integration System Based on Grid has been developed.This thesis analyses the architecture of Data integration and several mainstream Data integration technologies. The superiority of integration of service oriented OGSA architecture that we put forward also analyses the development and the problems of social insurance information system and gives the method to solve the problems. In term of the requirement of Social Insurance Information System, we studied and analyzed the inner infrastructure and operation process of the Middleware of Grid Globus and OGSA-DAI, and Deployed Social Insurance Information System under OGSA-DAI and implemented heterogeneous data integration in the simulated environment.
