The Research Heterogeneous Data Exchange System Based On BizTalk

With the continual improvement of enterprise information level, the integration demand among enterprises application becomes more and more. Owing to the arbitrariness of system development, the diversity of data structure and expression, the difficulty of information collection and exchange may be no less than developing a new system. A uniform standard needed to be built to realize the data exchange among enterprises application.In real life, technology and standards change with each passing day.Therefore, it is essential important to ensure that the construction of solutions is based on generally accepted protocols and file formats. Equally important, the solution should ensure that it can be integrated with as many business partners, applications as possible, run safely on the Internet, and expand with business growth. BizTalk is such a standard that it can meet these requirements more efficiently.The data exchange technology was analyzed, heterogeneous data exchange beween enterprises was researched. Comparing the difference among data exchange standards, the heterogeneous data exchange model based on BizTalk was implemented using BizTalk technology.The model adopted WebService to integrat with external system.The system ,which provides XML file directly,exchanges with other enterprise after submiting XML Schema to BizTalk exchange center.For the system ,which doesn't provide, a client was designed to exchange with database(such as SQL database).Meanwhile, the method of security problem and binary file, image transmission problems were given .Finally, the data exchange system is applied, limitations and further improvement were pointed out.The main content of the thesis are:1) The heterogeneous data exchange systems based on BizTalk and client were designed;2) The research of data conversion, mapping and business process;3) The implementation of data exchange system based on BizTalk.
