Question 7

An alternate key is not a candidate key.

Answer

False

Reason — An alternate key is a candidate key. A candidate key that is not chosen as the primary key is called an alternate key. In other words, any attribute that is a candidate for the primary key, i.e., which is capable of becoming a primary key but is not a primary key, is an alternate key.
