This book covers the various aspects of persisting SanFrancisco object states in a relational database. During the prototyping phase of an application, POSIX support may be used for simplicity. However, at deployment time, the data should be persisted in one or more relational databases to optimize performance, scaleability, and reliability.
You will develop an application that will be one of the following types:
• An application that is independent. It does not share its database with any legacy system. In this case, you can develop your objects without considering any external constraint.
• An application that shares its database tables with a legacy system. The extent of impact of legacy integration with your application depends on how tightly the legacy system needs to be coupled with your application.
