To exploit the power of a JDO implementation to the full takes experience. This section will demonstrate how to exploit JPOX to the full.

• Normal Collection - This takes a couple of classes that have a 1-N "Normal collection" relationship between them and analyses the various options for persistence with JPOX.
• Inverse Collection - This takes a couple of classes that have a 1-N "Inverse collection" relationship between them and analyses the various options for persistence with JPOX.
