recently I released a new version of SqlSpec which supports a few more platforms (SSIS, Teradata, SQLite).
SqlSpec is a database documentation tool. Here are the platforms it supports now:
Microsoft SQL Server 2000/2005/2008
Microsoft Analysis Server 2005/2008
Microsoft Report Server 2005/2008
Microsoft Integration Server 2005/2008
Sybase SQL Anywhere
Raima RDM Server
quite a few! some of these DBMS don't even have a forum here at dbforums!
See the link in my sig if you are in need of docs or a data dictionary for one of the platforms above, thanks for reading!
