Part I. Programming with the Direct Persistence Layer

This section discusses how to build an application using the DPL. The DPL is ideally suited for those applications that want a mechanism for storing and managing Java class objects in a JE database. Note that the DPL is best suited for applications that work with classes with a relatively static schema.

The DPL requires Java 1.5.

If you are porting an application from the Berkeley DB API, then you probably want to use the base API instead of the DPL. For information on using the base API, see Programming with the Base API.
