public interface Entity

This is the interface for an entity that can be loaded from or saved to a database. Typically you may want to use EntityBean but for legacy technologies such as JPA you have to use standard Java Beans that can directly implement this interface without implementing EntityBean. Each such Entity can be identified uniquely by its primary key.
