На мой взгляд,
очень интересный подход в обучении DB2.

Learn or teach the basics of DB2 and relational database with an interactive game called
The DB2 Detective Game.

The game teaches relational database concepts and shows how technology can be applied to solving real-life problems (the game's theme is a crime investigation).

This tutorial has been updated for DB2 9.
