I don't think what you're looking to do is one of the strengths of Toad for Oracle v9.6. For a "whole database", you'll most likely want a dedicated modeling tool. Many of the available tools are listed here: http://savage.net.au/Ron/html/drawing-tools.html ...including Toad Data Modeler (separate from Toad for Oracle that you already have), with which I have done what you are requesting. I'll leave it up to you to judge for yourself. I'm sure your Quest rep can get you started. HTH! GL! Rich Disclaimer: I'm a Toad bigot, using it since v4.
