The Design And Implementation Of Data Exchanging Based On Web Service

It is the question which needs to solve in computer research area that the realization of integration and sharing of government information and the solution of "the information isolated islands" between community various departments. The goal of data exchanging lies in the realization of the merge and sharing of data message resources, equipment resources, human resources and so on between different systems.The article was based on the community system of one district. It analysed "the information isolated islands"problem in the Community Information process and presented a module in base of the analysis of the two data exchanging modules. In the same time ,WSDES (Web Services Data Exchanging System )was designed which used Web Service and XML technology .The unified data exchanging form XML Shielded the difference of heterogeneous data sourceses and Services were published in way of Web Serrvice to realize data sharing and data integration between community various departments with previous applications making no change.Besides,roles were used to make data publishing and sharing convenient. WSDES was sure to achieve the goal of data exchanging among departments and units, as well as to preserve the existing systems to the most degree. The article analysed and designed data exchanging component in the server and data conversion component in the client to realize data access of heterogeneous data sourceses and data conversion between heterogeneous data form. It analysed data interactivation between server and client.
