Design Patterns: Data Access Object - Oracle.

If you know that a DAO class will only ever use JDBC databases (for example), the generic DAO class can be hardwired into the application, instead of selected by a factory. For maximum flexibility, the sample application uses both a factory method and a generic DAO. Encapsulating non-database data resources as DAO classes..
