一种基于关系的XML文档模型映射方法
Model mapping scheme for XML documents based on RDBMS
摘要
Abstract
On the basis of analyzing existing mapping schemes, this paper proposed a new model mapping scheme from XML document to relational database. According to the node type, mapped the information of each node in XML document to diffe-rent table in relational database. All non-leaf nodes stored its child nodes,which could effectively reduce the document restruc-turing time, while all leaf nodes were grouped, which could effectively reduce the cost of the node join operation. The results of experiment show that this scheme has a higher efficiency than existing mapping schemes in document restructuring and query. It is universal and can be used to process any XML document.关键词
