Analysis And Design Of Data Exchange Platform With Some Key Problems Based On XML

With rapid development of information and network technology, the situation of heterogeneous is more and more critically in the enterprise and government. Because their information management systems is lack of unified deployment when they are developed. It is an urgent need for all enterprises and their subordinate departments to make timely information access and sharing in the trend of IT application. The scheme of data exchange platform is effective pattern to solve this problem. It can be protected the investment of original information system and continued the used habit of the system. More important, it can be shorted the development cycle, exchanged data, and sharing information.This paper originates from the project of data exchange platform in science and technology center. 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 are 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.In short, the data exchange platform is build based on XML. It is facilitate to maintenance, expansion and transformation of the system in the future. It also made full consideration to the security issue for system, and provides a safe, reliable and efficient protection to sharing of data in the network environment.
