User views are included as part of which schema?

  • A.Internal
  • B.Conceptual
  • C.External
  • D.None of the above.

Answer: C

Correct answer: External

An external schema is the view a particular user group has of the database - the subset they may see, presented in the form that suits them. Several external schemas sit over one conceptual schema, which is what allows different groups to be given different views of the same data.
