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)
“Make-believe is the avenue to much of the young child’s early understanding. He sorts out impressions and tries out ideas that are foundational to his later realistic comprehension. This private world sometimes is a quiet, solitary
world. More often it is a noisy, busy, crowded place where language grows, and social skills develop, and where perseverance and attention-span expand.”
—James L. Hymes, Jr. (20th century)
