【摘要】 随着世界经济全球化的发展，电子数据交换已成为企业参与贸易竞争的重要手段，企业迫切需要在更大范围内实现资源共享与数据交换。由于企业的平台和数据模式各不相同，传统的数据交换方式已经越来越不能适应现代电子数据交换的需要，基于可扩展标记语言XML和Internet的新一代数据交换系统是未来的发展方向。 本论文采用XML和J2EE等技术构建了一个适合电子商务应用的通用数据交换系统。在数据交换中，发送端的企业首先将XML数据文档发送到数据交换平台，由平台转换成符合接收端的企业数据模式的XML文档后发送给接收端，从而实现了企业间异构数据的交换。异构数据的转换由数据交换平台完成，企业不需要了解彼此的数据模式，因此本系统适用于任意企业间的数据交换，是一个通用系统。通过本文构建的系统在企业一对多发送数据的时候尤其便利。 论文首先介绍了电子数据交换的发展现状和电子商务的演变，并研究了企业间数据交换的特点和涉及到的技术。在此基础上设计了通用数据交换系统的功能，分层结构模型和数据交换的过程模型，并对具体实现进行了初步分析。然后给出了系统的具体实现，包括客户端生成XML Schema、XML文件和服务器端交互层组件、业务层组件和XML文档模式转换的实现等。接着给出了数据交换系统的部署方法并对数据交换平台进行了测试。测试结果表明本平台可以完成基础的数据交换功能。论文的最后对全文的研究进行了总结并分析了有待改进的地方，做为将来研究方向的参考。更多还原

【Abstract】 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.更多还原
