Research And Application Of E-Government Model Based On WEB SERVICES

E-Government system can transplant government service to the Internet, and change directorial function of government into service function .It is a very important criterion of evaluating a country's standard of informatization. Although our governmental standard of informatization, popularized by lots of departments of government, has made quiet great progress, there are also many questions that need settling urgently, for example, information construction without whole programming, existent system with over many isolated subsystems, existent system without expansibility, etc. On the other hand, development of distributed technology creates Web Services technology that can be used to construct loosely coupled distributed system. A series interrelated Web Services technology can be named as "Web Services stack", including SOAP for transferring services, WSDL for services description and UDDI for services discovery integration and so on. Web Services implement communication between applications and services by XML-based SOAP, and descript services by XML-based WSDL files. After putting forward an E-Government model based on Web Services (WS-EG) and showing two examples based on the model, this paper deals with many technology questions such as framework of E-UDDI model, how to transfer existing codes into Web Services, Web Services-based database access and so on, and expatiates the design process of Fire Management Information System (FMIS), especially some important subsystems such as inputting information subsystem, batch amending subsystem, people translating subsystem, organizational system management subsystem, data synchronization subsystem etc. Lastly, the paper analyzes the action of Web Services Collections in FMIS and WS-EG..
