Extra info for Pro EJB 3: Java Persistence API
If the entity manager encounters a problem doing this, then it will throw an unchecked PersistenceException; otherwise the employee will be stored in the database. When the persist() call returns, emp will be a managed entity within the entity manager’s persistence context. Listing 2-3 shows how to incorporate this into a simple method that creates a new employee and persists it to the database. Listing 2-3. persist(emp); return emp; } This method assumes the existence of an entity manager in the em field of the instance and uses it to persist the Employee.
The configuration for an entity manager is bound to the EntityManagerFactory that created it, but it is defined separately as a persistence unit. A persistence unit dictates either implicitly or explicitly the settings and entity classes used by all entity managers obtained from the unique EntityManagerFactory instance bound to that persistence unit. There is, therefore, a one-to-one correspondence between a persistence unit and its concrete EntityManagerFactory. Persistence units are named to allow differentiation of one EntityManagerFactory from another.
Inheritance relationships between full-time and part-time employees Inheritance presents a genuine problem for object-relational mapping. We are no longer dealing with a situation where there is a natural mapping from a class to a table. Consider the relational models shown in Figure 1-6. Once again we demonstrate three different strategies for persisting the same set of data. Arguably the easiest solution for someone mapping an inheritance structure to a database would be to put all of the data necessary for each class (including parent classes) into separate tables.
