virtual private database (VPD)
Virtual Private Database (VPD) is a database security feature that
is built into an Oracle database
server, as opposed to being part of an application that is accessing the data. The user is only
allowed to see the data they have been given permission to see.
VPD uses application contexts to provide row-level security and fine-grained access
control based on a company's security policies. Application contexts are simply key value pairs
that are created in a defined namespace. VPD was first introduced
in Oracle8i.
