sql server - Should I create the support objects required to use database diagramming? -


when click on database diagrams in sql server management studio 2008 r2, databases tell me following message:

this database not have 1 or more of support objects required use database diagramming. wish create them?

are there concerns (i.e. security?) in doing so? databases aren't mine

if these databases aren't yours, suggesting not schema changes. can critical issue.

for instance: adding foreign key table, can cause massive error , bugs app, without 1 know why.

any modifications or adding new things real , taking effect immediately.
