Research On XML-based Data Interchange Technology In Electronic Government

In the process of earring out e-governmet, we are often faced with many practical problems, especially those application system and software products ,which have many differences in system infrastructure, platforms for operating and database , what have been developed or purchased by government in all levels for their own need. Because of this , the interchange among different systems can't be carried out, and a series of isolated information islands accumulated. If this situation can not be improved by proper measures, the implement of e-government can not use the existing system, and if we construct a new system , their will be an enormorous waste of the former investment as well as the lost meaning of the e-government construction and implementation.Extensive markup language provide an opening-standard for the satety and efficient electronic government. Because improving the weakness of the traditional data interchange, it brings the small-medium enterprise into the electronic government market. The XML-structured data can be separated from the business rule and the expression form, expediently for the data exchange and data process. So the XML is regarded as the standard of data exchange when it just appeared.Firstly, we deeply analysis the extensible markup language and it's key technology for data exchange, combined with the characteristic and requirement of e-govemment affairs system, studied the application of XML in these system, put up a XML-based data exchange model for different database system in e-government affairs system. Secondly, we realize the model under J2EE platform aligned with the programming theory, and applied it in district-level authority administration service system. At this level, the system not only have the ability for multi-platform, but also can exchange data for different database system. Most of all, the system can link with the other department's OA system in the area. It promote the efficiency of the government as well as put up the good image of the government.
