Multivalued dependencies create harmless anomalies that should be noted, but do not always need to be eliminated.

  • A.True
  • B.False

Answer: B

Correct answer: False

Multivalued dependency anomalies are not harmless. Two independent multivalued facts in one relation force every combination of them to be stored, so adding one value of the first requires a new row for every existing value of the second, and the redundancy grows as their product. Splitting the relation removes the problem entirely.
