在J2EE体系结构上构建基于XML的数据交换系统

Building an Xml-Based Data Exchange System Under J2EE Architecture

本文介绍了一种在J2EE体系结构上实现的基于XML的数据交换系统.系统实现了一个统一数据交换接口,各种类型的外部数据结构(包括HTML、WML)都可以通过格式转换而变为系统可以识别处理的XML文档.同时,系统自定义了一套XML标签来标记各个XML文档,根据这些标签的内容来对XML文档进行处理.最后,本文还描述了系统中XML文档与传统关系型数据库的数据交换与格式转换,并指出了一些有待解决的问题.

This paper introduced an xml_based data exchange system under J2EE architecture. This system implement a uniform data interface and many kinds of outside data structure can be transformed to XML document. This system also define a set of special XML tags to mark the XML document and deal with the XML document according to the content of the tab. At last, this paper describe how XML document and tradition database exchange these data and point out some problems waiting for solve
