J2ee E-government Application Systems Integration Platform-based Design And Realization

Since 1990s, our government has been engaged in utilizing information technology to improve government operation efficiency. Howerer, due to history causes, the problems of "Information Island" and "Overlap Construction" are commonly seen in the informationlization process of government affairs, which greatly hinder the development of E-government in our country. In order to solve these problems, it is impossible to abandon existed infrastructure and application systems completely and adopt new products and technologies to rebuild infrastructure and application systems. The most practicable and feasible method is to utilze advanced information integration platform to "integrate" existing infrastructure and application systems.Through searching the data and definition on E-Government from home and abroad sources , the paper analysed the problems existing in E-Government in detail. Based on the solid research on the E-Government theory and the case study, the article generates the Government application integrate framework as well as the steps and ways on how to process. The framework not only could lower the cost sharply, but also could efficiently utilize the existing data and application system to make the data/information sharing available within internal departments of the government without sacrificing the normal operation of the existing system, which will be. a great promotion of the development of the E-Government in China.
