Chinook Database on CodePlex

The other day I was browsing around CodePlex and found a wonderful tool for learning SQL Server or for integrating your applications with SQL Server. The Chinook database, while small, has some cool appeal to it. It has all the major components you need. You can work on reporting for invoicing, sales, inventory, just about anything.
