从XML模式到关系模式的影射

Mapping from XML Module to Relation Module

XML在关系数据库中的存储问题是XML研究领域中的一个重要问题。该文在总结多种影射方法的基础之上,提出了一个利用DTD文档,在关系数据库中通过多阶段XML文档信息的提取与变换,最终实现XML模式到关系模式的影射。该文对于影射中的一些难点问题,如集合值的影射、递归元素的影射、关系表的分散等方面提出了解决办法,实现了一个较为完整、高效的影射方案。

Storing XML data in relational database is an important problem in XML field.On the base of several map-ping ways and parsing of DTD documents,the paper comes up with a way that implements mapping from XML data module to relational data module through multi-phase's abstraction and transformation of XML information in a rela-tional database.This paper brings forward some solutions to those difficult problems ,such as set value mapping,recursion mapping,relations' fragments,and achieves a more complete and efficient mapping project.
