Note : A Virtual Private Database (VPD) is a shared database schema containing data that belongs to many different users and that each user can view or update only data he or she owns.

A VPD deals with data access

VPD controls data access at the row or column level

SQL implements VPD using the VIEW object while Oracle10g provides specific functions for row-level security and fine-grained access.

Example of purposes of using virtual private databases:

Security requirements necessitate data access be restricted at row or column level

One database schema serves multiple unrelated groups or entities

A VPD deals with data access: VPD controls data access at the row or column level
