SQL-DB-Designer

This tool creates a diagram in a GML- or GraphML-format from a Microsoft SQL database. This file can then be edited with an Editor like yEd Graph Editor.
The GraphML file can be edited directly with the online version from yEd.
The relations are displayed in color, resulting in a clear diagram. The color of each relation can be edited as you requires!

Please make sure, that TCP/IP is enabled on your SQL-Server!
