Virtual private database

A virtual private database or VPD masks data in a larger database so that security allows only the use of apparently private data. Separate sites, departments and/or individuals transparently see and manipulate data specific to their needs and to their security classifications. The implementation by Oracle of this concept actually applies some extra filtering conditions to the query issued by the database user.
