基于eMTM的XML与关系数据库双向映射策略

The Bi-directional Mapping Algorithm between XML and RDB based on eMTM

在服装业需要在Internet环境下实现信息化的背景下,对来源复杂、范围广泛的三维人体数据来说,需要使用XML作为数据交换标准来采集数据,并使用XML与RDB交互来实现数据存取。根据eMTM的实际需要,对比XML与RDB的特点,提出了XML与RDB的两层双向映射策略,其实质是通过静态转换、动态检索两个层次的数据处理,实现既能从XML到RDB、又能从RDB到XML的双向数据映射,实现XML与RDB的互通互访。

As the Apparel Industry needs to apply the information technology on the base of Internet, the industry demands a 3D Human Body data-exchange standard in XML to gather the data, because of the 3D Human Body data coming from complex and wide datasources. The industry also needs to realize the data access by the interaction between XML and RDB. After the characters of XML and RDB having been compared, the Bi-directional Mapping Algorithm between XML and RDB has been put forward to satisfy the real need of eMTM. It can not only convert XML into RDB, but also convert RDB into XML, through any data processing in two tiers which are static data transforming and dynamic data querying. It deals with the communication problem between XML and RDB.
