I think that there is plenty of room in NorthWind for both simple and complex tables. A well designed database should include simple tables as well as complex relationships, data types, etc. When you are learning basic table structure, you don't need to know about stored procedures - but they can still be in the database, waiting patiently for you to get around to them. Viva complexity! - as long as we keep the simple stuff. I would love to have samples available for some of the medium to heavy-duty concepts that SS supports!
