Add a database modeling tool similar to the ERWin or ERStudio products. Do not use the SSMS Diagram tool or Visio as an example.
Make sure the tool supports physical notations such as IDEF1X, IE, and DM. The tool needs to be as sophisticated as ERWin and ERStudio and not a non-standard tool such as SSMS Database Diagram tool or a generic drawing program such as Visio that is essentially useless for creating Enterprise ERDs.
I want to personally thank you for taking the time to share this suggestion. Since the suggestion you raised has not gathered many votes, the Visual Studio team is closing it at this time.
If you would like us to reconsider this, please create a new suggestion. Again, thank you for sharing with us!
