Oracle 10g Virtual Private Database

Column-Level Privacy - It increases performance by limiting the number of queries that the database rewrites.  Rewrites only occur when the statement references relevant columns. This feature also leads to more privacy.

Customization - With the introduction of four new types of policies, you can customize VPD to always enforce the same predicate with a static policy or you can have VPD predicates that change dynamically with a non-static policy.

Shared Policies - You can apply a single VPD policy to multiple objects, and therefore reduce administration costs.
