Hi all, Could anybody do me a favour? I have a blocked question to integrate the ER model to Database Model. I created some ER models of some sub-functions with Visio,then I created a Database Model to integrate the ER models, I added the sub-ER source model files to the Database model project. But I can not find any Entities, such as table,view, in the database model project, I only see the tables and views in each Sub-ER source model file. ' I read the online help of Visio. It told me just click the menu item: "Database"->"Project"->"Create". but I cannot find the menu item. Why??? How to integrate the ER Models to Database Model? Anyone can give me a hand? Thanks very much, Frank
