Abstract:

With the rapid development and application of information technology in association with diverse technologies,complex application and distributed calculation,many application systems have been built up either on the distributed network or with a variety of heterogeneous resources.The information systems of e-government sectors are mostly developed using different tools,at different development platforms,during different periods and by different developers.This will inevitably bring great inconvenience to the future applications of associated integration.In order to ensure data consistency and improve data sharing,one need to create a data exchange platform covering a variety of heterogeneous systems.This paper,through in-depth research and analysis,proposes specific technical solutions to the integration of multiple information systems.
