Heh. Nice to see someone who likes TOAD (I assume for SQL Server?) Personally I hate the product, but I know other people disagree. My issue with TOAD is that it tries to be a "jack of all trades" (and hence...) I have to admit I didn't even realise TOAD had a database design part, although it's been several years now since I had to use it, so it may have been a more recent addition.
I know a bunch of Oracle DBAs who are moving to SQL Server, and keep insisting that they need the SQL Server version of TOAD. I've been telling them to learn Management Studio instead. Perhaps I need to revisit that?
