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)
“Denouement to denouement, he took a personal pride in the
certain, certain way he lived his own, private life,
but nevertheless, they shut off his gas; nevertheless,
the bank foreclosed; nevertheless, the landlord called;
nevertheless, the radio broke,
And twelve o’clock arrived just once too often,”
—Kenneth Fearing (1902–1961)
