摘要
介绍如何将XML文档转换成标签有向图。讨论基于这种标签图将XML数据库映射成关系数据库。这种映射模式包括两个步骤,即属性映射和值映射。最后讨论在这种映射模式下,针对数据库的几种操作。
The paper introduces how to convert XML documents to labeled directed graph, discusses how to mapping XML database to relational database based on the labeled directed graph. There are two steps in tiffs mapping schema tecimique, i.e. attribute mapping and value mapping. Finally, the paper discusses several operations on database base on this mapping schema technique.
