Model mapping scheme for XML documents based on RDBMS
一种基于关系的XML文档模型映射方法

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 restructuring 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.
