The Research And Implement Of A General Data Exchange System

With the development of economic globalization, electronic data exchange has become more and more important for enterprises to take part in the trade competition. Enterprises want imminently to share their resources and exchange data in a wider range. Because of the platform and data schema differences, traditional data exchange systems are no longer suitable for the requirements of the contemporary commerce. So their places will be taken by the new XML & Internet based data exchange systems.This thesis constructed a general data exchange system for the e-business based on the XML & J2EE technology. In a data exchange process, the source enterprise firstly sends the XML data document to the data exchange platform, then the platform converts the XML document into a new document in accordance with the schema of the target enterprise and sends it to the target enterprise. Thus the data exchanges among enterprises were realized. The conversion of XML data from one schema to another is handled by the data exchange platform. It is no need for the enterprises to know about data schema of eachother. So this system is fit for the data exchange among random enterprises and is a general system. The system is especially convenient when making a one to multi-enterprise data exchange.In this thesis, we firstly introduced the developing actuality of electronic data exchange and the e-business evolvement. Secondly we studied the specialty of business-to-business data exchange and related technologies. On the basis of previous study we designed the function, layer model & data exchange process model of the general data exchange system and made an elementary analysis of the actual implement. Then we gave out the actual implement of the entire system, including: generating XML schema file and XML file at the client side and coding the interactive layer component, the application layer component & the implement of XML file schema conversion at the server side and so on. At the latter part of the paper, we gave out the method of deploying the data exchange system and tested the data exchange platform. The test result shows that the platform can fulfil the need of basic data exchange. At last, the thesis concluded the research and analyzed the faultiness of the data exchange system as a direction of further research.
