Multivalued dependencies should ________ be eliminated.

  • A.always
  • B.commonly
  • C.seldom
  • D.never

Answer: A

Correct answer: always

A multivalued dependency means one relation is carrying two independent multivalued facts about the same key, which forces every combination of the two to be stored and produces genuine anomalies. Splitting the relation so that each holds a single theme removes them entirely, at no cost in information, so there is no reason to tolerate one.
