How can I find out what the datamodel is behind the System Tables
(SysColumns, SysObjects, SysDatabases, etc.). I once came across a question
about finding out what the default value for a certain column in a certain
table was. There was talk about doing some heavy parsing of the result set
after using stored procedure sp_help(text). And even then it was not sure
that the desired result would be achieved, they said, leaving one to the
choice of looking up the actual SQL code.
However, after looking up some documentation on the System Tables and
guessing from there on where I might find the desired information, I found
out that one may find the default value for a certain column in a certain
table (or any other object for that matter) in the SysComments table. It
would have been a lot easier to find this out if I had had a datamodel of
those System Tables. Now, before using ER Studio, I was wondering if this
datamodel exists and if so, if it could be shared with the community at large.
Many thanks in advance,
Wilfred Damhuis

I have no idea how well known it is (according to the text in the link,
it's "very popular") but I only discovered it last week
