The reversetutorial_database.properties, reversetutorial_database.script, and reversetutorial_database.data: These files make up a Hypersonic SQL file-based database with the schema outlined above. The database is already populated with lots of magazine data representing your shop's inventory.

reversetutorial.JDOFactory: Provides access to a properly configured javax.jdo.PersistenceManagerFactory .

The PersistenceManagerFactory class is the main entry point into the JDO framework. Persistence manager factories provide a mechanism for obtaining individual PersistenceManager instances, through which a user can find objects in the underlying data store. See the javax.jdo Javadoc for a more in-depth discussion of JDO in general and the PersistenceManagerFactory class in particular.

reversetutorial.Finder: Uses JDO to execute user-supplied query strings and output the matching persistent objects. This class relies on persistent classes that we haven't generated yet, so it won't compile immediately.
