Zhejiang Tonglu E-Goverenment Data Exchange Palform

With the development of E-Government, the government departments need to exchange their data urgently now, not only to achieve various functional departments of the data exchange between systems, but also the functions of government departments and application systems external services for data exchange system.This paper originates from the project of data exchange platform in Zhejiang TONGLU E-government. Through the research and analysis, I designed a solution for data integration base on XML. It meets the needs of data exchange platform. It can be pointed out three key problem in the process of implement to analysis this architecture and the process of integration first, and then analysis and design these problems. There is the formulation of data standard, the implement of data exchange and the security of the platform. The data standardized is designed by the detail investigation to the various systems of science and technology center, particularly in its data resources. And it is designed by following the laws and principle which is easy to expanse. The sharing data which extract from the subsystem was transform to this format in order to share it conveniently. Data exchange is using XML and its related technology to implement the data exchange from the business systems to central database. It is the key of the data integration of the whole system. The various subsystems can send message to middle database. It is defined a document format firstly, and use templates to convert into the XML data document and Schema mapping file, and transmit it to the central database. The security of the system is an essential part in the process of the implement. The paper considers access control mechanisms of the system in detail, and then designs WS-security to sensitive information. It also designs a security filter data interface and malicious information filtering to protect the security of the system.
