Which is not a type of data management technology?

  • A.Relational
  • B.Rational
  • C.Object-oriented
  • D.Dimensional

Answer: B

Correct answer: Rational

Relational, object-oriented and dimensional are the three data management technologies a logical design may target, each with its own structures and its own products. Rational is not one of them - the similarity of the word to relational is the whole of the trap.
