XML与异构数据转换技术探讨

提出了异构数据库数据转换的问题,对可扩展标志语言XML进行了简要的说明,介绍了利用可扩展标志语言XML文件作为中间数据存储文件进行异构数据库间数据转换的机制,并给出了通过文档对象模型DOM和XML规范Schema文档以及XSLT样式表文件进行异构数据库数据转换的实现方法。与传统的异构数据转换方法相比,本方法具有开放性、移动性、适应性、可扩充性以及易于维护等特点,应用前景更加广阔。

Discussion of XML and Heterogeneous Data Conversion Technique

This paper puts forward an issue of heterogeneous database's conversion,and simply introduces XML.It also introduces the mechanism of how to use XML file as mid-data storage file during conversion of heterogeneous database.A realization of how to convert heterogeneous database by DOM,XML Schema Document and XSLT file is provided in this paper as well.Comparing with traditional methods of heterogeneous database conversion method,this method has such characteristics as openness,mobility,adaptability,expandability ang easy-maintainability,and it has wider foreground.
