title: Should I create the support objects required to use database diagramming?
body: <p>When I click on database diagrams in SQL Server Management Studio 2008 R2, some databases tell me the following message:</p>
  
  <blockquote>
    <p>This database does not have one or more of the support objects required to use database diagramming. Do you wish to create them?</p>
  </blockquote>
  
  <p>Are there any concerns (i.e. security?) in doing so? The databases aren't mine</p>
