This is something I asked during an interview. While we were talking about system databases, I questioned interviewee that how get information related to tables exist in system databases. The answer was "Simple, we can make a database diagram and can use it for understanding structures and relationships". Can we really do it?
Here is the question for the week? Can we create database diagrams on system databases?
The answer is simple, but not the answer given by interviewee. It is not possible. SQL Server does not allow us to generate diagram or script system tables. Even if you try to use Generate Script it will not list out system tables.
See, how it appears when trying to script the msdb database. As you can see, there is no options to get even script generated on system tables.
