一种基于RDBMS的XML数据的存储方法

XML作为一种数据交换的标准在互联网上推出,使得XML数据和数据库的相互交换成为必要:一是因为WEB中大量的多样化数据需要进行有效的存储和管理;二是因为在现有的数据库中存储有大量的数据并且需要将这些数据转换为XML发布到WEB中。论文提出了一个基于关系数据库的数据转换框架,基于数据的完整性讨论XML数据存储策略。建立一个XML通用数据模型,把文档树分解成多个节点,根据一定的映射规则存储到关系表中,从而不用考虑文档的模式信息(DTD、XMLSchema)。最后通过一个具体的文档实例来说明这种策略的有效性。

An Approach to Storage XML Documents Using Relational Databases

XML is fast emerging as the dominant standard for representing data in the world wide web.That makes it necessary for the exchange of XML document and databases.This paper describes a general storage method for XML documents using RDBMS.The storage method decomposes tree structure of XML documents into nodes,and stores them in relational tables according to the node types.By using this method,being independent of DTDs or element types,any XML documents can be stored in databases.It also performes experiments using XML documents on Books to show the effectiveness of the methods.
