The Relational Model and Normalization - Technical MCQs

Q1:

If attribute A determines both attributes B and C, then it is also true that:

A A → B.

B B → A.

C C → A.

D (B,C) → A.

ANS:A - A → B.

There is a different between determines and determine of.

If determine of then B->A but here determines B and C so A->B.
