9  * This simple sample shows how to use the ODMG interface of ozone. The are
10  * a few things in the ozone ODMG interface that are not fully ODMG 3.0
11  * compliant. So, care must be taken when writing code against this API.<p>
12  *
13  * First, database objects do not implement any database specific interfaces.
14  * This means the actual database connection cannot be simple retrieved by
15  * calling the database() method of the database object.
