数据集成中XML模式和关系模式映射模型研究

Research on Mapping Model between XML Schema and Relational Schema in Data Integration

针对数据集成遇到的数据交流难问题,文章首先介绍了XML技术的优势,并就如何利用其优势来解决XML文档和关系数据库之间的数据转换问题进行了分析。进一步研究了XML和关系数据库之间的基本映射方法,在此基础上建立了XML模式和关系模式之间双向映射的模型,并给出了模型的实现。

In view of the difficulty of data exchange in data integration, this paper introduces the advantages of XML technology firstly and then analyzes how to solve the problem of data transformation between XML document and relational database. The basic mapping methods between XML and relational database are deeply discussed. Based on the discussion, the bidirectional mapping model between XML schema and relational schema is founded and realized.
