Re : Am I overseen ?

Hi,

You might want to have a look at DdlUtils that does similar things that you want to do: compare databases schemas using XML files and synchronising the schemas.
Interesting tool ! !

What kind of tools are you familiar with? I'm guessing you could
write something in perl or php to do it. Or do you want to do it in
sql? I'm sure you could do it in plpgsql or some other pl/language,
if you want it all in the db.

But I'm not that familiar with UML as to say what's the best approach.

Normally when you get thundering silence, you've asked a question no
one feels real qualified to answer, and rather than answer it halfway,
they just leave it for the next guy to get.
