/**
 * Example for persistence with the "inheritance per class" strategy
 * 
 * The "Inheritance per class" strategy causes subclasses to share the database tables
 * of their parent classes. In order to be able to tell the types of the entries apart, a
 * discriminator has to be used.
 * 
 * Thus, a single table is created that has the columns of all entities that share it (causing
 * a tradeoff between database size and access speed).
 * 
 * "inheritance per class" needs to be declared in the topmost entity that should share the
 * common table. The setting is then inherited by children.
 * 
 * The example below shows the declaration of custom values; inheritance per class
 * declarations have been added to sub-entities in order to override default values. This would
 * not have been necessary.
