Design And Implementation Of Data Exchange System Based SOA, Web Service And Java

With development of Information Technology,"Information detached island"is the biggest one of these problems. It makes information not to be shared, work not to be cooperated among enterprises, which makes great waste of information resource and redundant construction of information. Therefore, to solve the problem,it becomes solution to set up data exchange system with multiple networks, and multiple platforms.The design and implementation of data exchange system based on SOA and Web Service is the main content of this thesis. SOA is the software architecture based on standard and loose coupling, and Web service makes real-time data exchange in multiple platforms more easily to realize. The whole architecture depends on design principle of SOA, which merged business process and IT technology well. And all modules of system are developed in Java platform, which makes system several characters of great progress, high efficiency, more open, security, and high migration in multiple platforms.At first, several problems of data exchange system are submitted to be solved: 1. security of network communication; 2. integration of old system; 3. integration of business process; 4. interactive data exchange; 5. high efficiency of system development. Then there are several technologies to be chosen for these problems, such as SOA, Web service, Java, and makes completed analysis and comparison for them, especially for SOA and Web service, demonstrate the function of these technologies in the system development, and provides a solution of data exchange based on SOA and Web Service. And in the third section, with SOA principles, the analysis and design of business process is used in the case. And model is built with UML. In the forth charter, the technologies are analyzed for the problems submitted, and system modules are divided and builded with UML, the function models are designed with Web Service soap,LDAP user Authenticate,XML digital singature, and these models are implemented with Java code, at last related problems are completedly finished. Finally, the conclusion of this thesis is made and shortcoming of system is discussed which makes the direction of research in the future. .
