Given the functional dependency R → S , R is called the determinant.
A. True
B. False
Answer: Option A
Solution (By Examveda Team)
Option1: TrueIn the relational model, a determinant is a set of attributes that uniquely determines the values of other attributes in a relation. In this case, the functional dependency R ? S indicates that the values of attribute R uniquely determine the values of attribute S. Therefore, R is indeed the determinant in this scenario.
Option2: False
If we consider the functional dependency R ? S, where R determines S, then R is indeed the determinant. Therefore, this statement is false.
Conclusion: The correct option is Option1: True. In the given functional dependency R ? S, R is called the determinant as it uniquely determines the values of attribute S.
