An intersection table is required to represent M:N relationships.

  • A.True
  • B.False

Answer: A

Correct answer: True

A many-to-many relationship cannot be represented by a foreign key in either table, since a single column cannot hold an unknown number of references. The intersection table resolves it into two one-to-many relationships, holding one row for each pair, with the two foreign keys together forming its primary key.
