XML is an emerging standard for Internet data representation and exchange. There are more and more XML documents without associated schema on the Web. An XML document without associated schema is called well-formed XML document. It is difficult to store and query well-formed XML documents. This paper proposes a new XML documents storage model based on model-mapping, namely XPEV. The unique feature of model-mapping-based storage model is that no XML schema information is required for XML data storage. Through XPEV's three tables: Path table, Edge table and Value table, well-formed XML documents could be easily stored in relational databases. XPEV model can make full use of the index technology of relational databases, and give a better solution for querying and storing well-formed XML documents using relational databases.
