In order to realize the mapping from XML data to relational database,a mapping scheme is proposed,in which any well-formed XML documents can be stored in a relationship mode of the fixed structure to realize the mode storage of the fixed relationship for XML documents with different structures,which is not affected by the constraints of DTD changes.Meanwhile,the Dewey coding and depth of the node are automatically inserted in the storage process.The XML document information can be extracted by using JDOM,the additional Dewey coding mapping algorithm is given,and the results indicate that the design is reasonable and effective.
