E.

F.
Virtual Private Database

Explanation:
Both Oracle Virtual Private Database (VPD) and Oracle Label Security (OLS) enable you to
restrict the datathat different users can see in database tables. But when should you use Virtual
Private Database and whenshould you use Oracle Label Security? Virtual Private Database is
effective when there is existing data you canuse to determine the access requirements. For
example, you can configure a sales representative to see onlythe rows and columns in a customer
order entry table for orders he or she handles. Oracle Label Security isuseful if you have no
natural data (such as user accounts or employee IDs) that can be used to indicate atable’s access

requirements. To determine this type of user access, you assign different levels of sensitivity tothe
table rows.
