Atlantis Schema Surf

Atlantis Schema Surf is a visual schema exploration tool, showing the dependencies between the objects in your database and the objects that they depend on. it is a free animated graphing tool which allows you to easily visualize the dependencies between the objects in your SQL Server databases in a live entity ER diagram.
Schema Surf, like its counterpart Data Surf, contains a "Surf Graph" which allows you to easily view an object and the connected objects in one of multiple layouts. You can click on any object in the graph, and that object then becomes the focus of the graph - with the graph then re-arranging itself around the newly selected object. Give Atlantis Schema Surf a try to fully assess its capabilities!
