Application And Research Of XML In E-government Data Exchange

The global network, the informationization advancement were changing people's life style, the Internet technology application as well as the electronic commerce swift development live work each stratification plane for the people to bring the profound influence. E-government oneself becomes the Government department to reform the development gradually the way that must be taken.Our country E-government's development meets two main difficulties: First is the information isolated island question; Second is E-government's integrated question. Is also the government various departments isomorphism or between isomerism platform the data exchange unification form, various departments system is isolated, cannot face the end-user to provide the "one-stop" work style service, the E-government does not have a perfect solution until now. The present paper the Nantong E-government system's promotion transformation which starts by March, 2006 is a background, introduced that the E-government data exchange the system design, realizes and some correlation techniques.In the last few years XML is the data format which and data exchange standard W3C proposed, XML has openness , from the descriptive and the platform independency, is called as "on the Web ASCII code", recently oneself becomes in the science and the service application the data expression standard, as well as application data exchange standard.The article selective analysis E-government data exchange application demand, has established the data exchange model, according to data exchange's principle, proposed the data exchange prototype system's design, and gave has realized the method.The article first aims at the domestic and foreign E-government data exchange technology the state of play, carries on the discussion on the tradition data exchange's characteristic and the existence question, pointed out that the data exchange platform research has the important value. Then introduced the XML technology's correlation theories, data exchange's concept, the E-government data exchange's necessity and the extant question, the E-government data exchange's application classification, and into the E-government data exchange process, XML and relational database's transformation has made the detailed elaboration.Finally just the data exchange prototype system applies in the electronic archives system, has completed an electronic archives transition system.
