Just realized I have all kinds of documenting tools for my DBCs in VFP but don't know (or have forgotten) how to go about this in DDT/SQL
( If none of this is already there, consider reporting an ER for the DDT)
But my real issue was : How do you document a SQL Server database. Found this, it is only $50 and seems to do the job very well. Free trial download so I'd be interested to hear what others think.
