E-government Web Service-based Data Exchange Platform For Research And Design

Along with the rapid development of information technology, the E Government become the hot spot which studied in recent years. And the information sharing and interconnection exchanges has become important issue which the current E-Government constructs faces day by day. When constructing the E-Government,it needs to solve the question of exchange between new construct system and original system.Therefor,it is urgent to establish data exchange platform for E-Government.When exchanging data for different format data, it needs the support of XML,this kind of public data format. Web Service may provide the convenience Web accessing interface.At the same time ,the SOAP (Simple Object Access Protocol)protocol which the Web Service adopted,can communicate based on HTTP protocol.Because HTTP wide uses in network, it make possible for web service provide connection. XML and web service technology the paper based on can realize data exchange of different format.It become a perfect solution of data exchange. The data exchange platform this article establishes just be based on the Web Service construction.The data exchange platform this paper studies can realize data exchange of different format. In the base of study a series of data exchange standard, it has proposed data exchange system structure based on XML and Web Service, and it has realized the electronic document form based on XML.At the same time, it imports network security in the data exchange platform, and constructs platform based on digital signature and status authentication. It has realized the different local area network data sharing and isomerism data conformity. For the convenience of the resource management in data exchange, it proposed the multistage data exchange platform to alleviat the pressure of overabundant information in exchange process.Based on the above research, it has built the data exchange platform for somewhere chemical industry garden area E-Government system. It can realize data exchange between the different department and can quite facilitate work.
