一种基于分层框架的XML发布方法

因特网的不断发展使得XML成为Web上数据交换和表示的标准格式,但是大量的商业数据仍然存储在关系数据库中。因此必须将关系数据发布成XML文档进行传输。提出了一种基于分层框架结构的关系数据库向XML的映射方法,并在分层结构中定义了一种XML模式图作为XML的概念模型。得到的XML文档能够很好地反映关系数据库的语义和各种约束并且没有引入数据冗余。初步实验结果表明方法具有较高的效率和较好的准确性。

A layered Framework-based XML Publishing Method

With the development of Internet, XML is emerging as a standard for exchanging and representing business data on the World Wide Web. However, most business data will continue to be stored in relational database systems. So some mechanism is needed to publish relational data as XML documents. A layered framework- based XML publishing method is presented in this paper, and a XML concept model is defined in the layered framework. The result of XML documents can reflect semantic and constraints in relational source while in- troduce no data redundancy. Experiment result can prove the method effective and precise.
