public class HSQLDBGameDAO

extends HSQLDBBaseDAO

implements org.dartra.framework.dao.GameDAO

HSQLDB specific JDBC based implementation of the Game DAO.

This implementation of the GameDAO interface does not support data retreival. Since data is stored in an RDBMS using JDBC, there is no need to recreate the game related objects to do statistical calculations on the game data in the database.

Player, Turn and Throw objects are dependents of the Game object and are thus mapped using a Dependent Mapping [Fowler], where Game is the owning object. Hit, Location and Score are mapped using Embedded Value [Fowler].
