title: Example database schemas for different db types
body: <p>I am looking for some adequately-complex sample database schemas that I could use for examples on my site <a href="http://sqlfiddle.com" rel="nofollow">http://sqlfiddle.com</a> (my current examples are pretty pathetic).  I know about AdventureWorks and Northwind for SQL Server, but I haven't really heard of any other "classic" examples for the other database types I support: Oracle, MySQL, PostgreSQL, and SQLite.  Ultimately, I would like both interesting/familiar schemas and some cool queries as the "Example Fiddle" for each type.  However, for the moment I'm only looking for the schema; the queries can come later.  Please point me in the direction of some of those interesting schemas, targeted for each database type.</p>
