A relation is in Boyce-Codd Normal Form (BCNF) if every determinant is a composite key.
A. True
B. False
Answer: Option A
Solution (By Examveda Team)
Option1: TrueIn the Boyce-Codd Normal Form (BCNF), every determinant must be a candidate key, which means it can uniquely identify each tuple in the relation. If a determinant is a composite key, it means it is made up of multiple attributes that together uniquely identify a tuple. Therefore, if every determinant in a relation is a composite key, then the relation is in BCNF.
Option2: False
If every determinant in a relation is a composite key, then the relation is in BCNF. Therefore, the statement that a relation is in BCNF if every determinant is a composite key is true.
Conclusion: The correct option is True.
