Create a Database Diagram Automatically

SmartDraw will build your database diagram for you automatically using data you can easily export from your database. First, get a CSV of your table definitions from your server (we'll even provide the scripts to do so) and then click the Automatic ERD Database Extension inside SmartDraw to create your database diagram. No drawing required! Shapes will not only be added, but they will be connected using all the proper notations. Learn more about automatic database diagrams.

The completed database diagram is fully editable. Move shapes around, add new tables, change copy, and so on. It's all intuitive.
