Abstract

Nowadays an information exchange on XML such as B2B electronic commerce is spreading. Therefore the systematic and stable management mechanism for storing the exchanged in formation is needed. For this goal there are many research activities for connection between XML application and relational database. A unified modeling methodology need to store the XML data on the variety database.
