【摘要】 XML逐渐成为Internet上数据描述和交换的标准。随着Web上大量数据用XML文档表示出来,有必要对这些XML文档进行操纵管理。为了结合关系数据库系统强大的数据操纵能力,论文在对XML文档的逻辑结构进行简要介绍的基础上,就XML文档特别是结构化XML文档与关系数据模型数据之间的互动映射作了深入探讨,特别是在数据结构和数据完整性约束条件的映射关系上作了更深一层的研究,提出了一系列基于XML本身的映射规则。更多还原

【Abstract】 XML has grown to the standard of data description and data exchange on Internet.With a large amount of data described in XML document on Web,it becomes necessary to control and manage those XML document.In order to combine XML document with the powerful data-controlled ability of the relational database,this paper introduces the logical structure of the XML document ,thoroughly discusses the mapping between XML documents,especially the structural XML documents and data of relational database.It especially discusses the mapping of the data structure and the data integrity restriction,and puts forword a series of mapping rules based on the XML.更多还原
