How we can find out Relationship of two system tables using database diagram in system databases

[Lost User]

AFAIK, it's not possible to make database diagrams in the system databases in Sql Express. I don't have a full version here to verify whether it's supported there, but I doubt it. FWIW, you can get a full map for the systables of Sql2k5 here[^].

You could look at the constaints on the foreign key. Does it allow duplicates, does it allow nulls?
