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. In this paper an unified design methodology based on EER data model for XML applications is proposed. For this goal, first a XML modeling guideline for XML DTD based on ER data model is introduced.
