摘　　要：分析了XML文档到关系数据库的映射方法,并提出了元素树和元素树节点与其他类型数据之间的映射算法.在此基础上建立了XML模式和关系模式之间的双向映射模型,并给出了双向映射模型算法,从而完成了XML与RDB数据转换.XML, as the carrier of data exchange between the database, a series of mapping rules by analyzing the mapping principles from the Relational Database to the XML document have been set up, and presented an approach based on DTD Element-Tree and a mapping algorithm between DTD Element-Tress and RDB, Based on this the bi-directional mapping model between the XML document and the RDB is built and a bi-dircetional mapping is given, which is used to complete the data transformation.

关 键 词：元素树 关系数据库 数据转换
