基于D-Schema的XML模式到关系模式的映射

D_Schema-based Mapping from XML Schema to Relational Schema

可扩展标记语言(XML)由于其简单性和自描述性使其正逐渐成为电子商务和因特网上信息表示和交换的标准。文中通过对XMLSchema结构和语法进行分析,提出了一种基于D＿Schema的XML模式到关系模式的映射方法,并对映射中的一些难点问题,如多值元素映射和递归元素映射等问题提出了解决方法。

XML (eXtensible Markup Language) is emerging as a de facto standard in e-commerce and Internet-based information presentation and exchange for its simplicity and self-description. After taking some analysis on the structure and syntax of XML Schema, this paper presents a mapping method from XML schema to relational schema based on D_Schema and also brings forward solutions to some difficult problems such as multi-value mapping, recursion mapping, etc.
