在数据集成中为了有效保证数据信息的完整性,基于XML Schema在数据集成中的优势,提出一种以节点生成树作为中间桥梁的XML Schema和关系数据库模式相互映射的算法,建立了XML文档和关系型数据库之间双向转换的映射模型,并给出了这一模型的具体实现方法.%In order to effectively guarantee the integrity of the data in data integration, based on the advantages of XML Schema used in data integration, this paper proposed a algorithm which put a node tree as a bridge of mutual mapping from XML Schema and relational database schema, establishes a two-way conversion mapping model between XML documents and relational database, and gives out a specific implement method of this model.
