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.
Famous quotes containing the words virtual and/or private:
“Tragedy dramatizes human life as potentiality and fulfillment. Its virtual future, or Destiny, is therefore quite different from that created in comedy. Comic Destiny is Fortune—what the world will bring, and the man will take or miss, encounter or escape; tragic Destiny is what the man brings, and the world will demand of him. That is his Fate.”
—Susanne K. Langer (1895–1985)
“Lisa Fremont: Surprise is the most important element of attack. And besides, you’re not up on your private eye literature. When they’re in trouble it’s always their girl Friday who gets them out of it.
L.B. Jeffries: Well, is she the girl who saves him from the clutches of the seductive show girls and the over passionate daughters of the rich?
Lisa Fremont: The same.
L.B. Jeffries: That’s the one, huh? But he never ends up marrying her, does he? That’s strange.”
—John Michael Hayes (b. 1919)
