摘要
XML作为一种数据交换的国际标准,已经贯穿于Internet应用的各个领域,如何利用XML实现异构数据库之间的数据交换已经成为一个重要的研究课题.本文在分析了异构数据库数据交换技术研究中存在的主要问题基础上,以XML SCHEMA作为XML与关系数据库的映射模型,提出了具有转换条件控制模块的异构关系数据库之间数据交换的解决方法,较好地解决了异构数据的交换问题.
As an international standard for data exchange over the web,XML has got into virtually all fields of internet application. How to use XML to realize data exchange between heterogeneous databases has already become an important research subject. Problems of data exchange technology between heterogeneous databases are analyzed. On this basis,SCHEMA is used as a mapping model for relation database and XML,which contains a transformation control module. With the help of the model,the data exchanges between heterogeneous databases can be solved fairly well.
