Abstract:To overcome the issues of the existing mapping methods being too strict to XML format requirements, this paper proposed a new method of mapping XML documents to relational database based on the modelmapping method. By making tokens for XML documents tree,data of coversion from mapping method would be stored into the two predefined structure tables.Discussed four aspects of logical data model,detailed design,mapping algorithm and experiment. The results of experiment show its ability of maintaining document structure effectively,performing first level sematic search is achievable,being a general solution for any tree data structure can be applied. ......
