You can code components to store state information in a remote database rather than in memory. Doing so offers several advantages, such as enabling failover and load balancing for stateful components, or allowing you to map relational data to a component interface using the EJB entity bean model.

The remainder of this chapter contains reference material that is useful in configuring stateful session components and entity components.
