A updatable view has its own data.

  • A.True
  • B.False

Answer: B

Correct answer: False

No view has data of its own, updatable or not. A view stores only its defining SELECT, and an update through it is translated into an update on the underlying tables. That is precisely why updatability is restricted: the DBMS must be able to identify the row of the base table to which the change applies.
