Q. If every functional dependency in set E is also in closure of F then this is classified as
A. FD is covered by E
B. E is covered by F
C. F is covered by E
D. Fplus is covered by E
A. FD is covered by E
B. E is covered by F
C. F is covered by E
D. Fplus is covered by E
Answer: B. E is covered by F
Functional dependency is a relationship that exists when one attribute uniquely determines another attribute. If R is a relation with attributes X and Y, afunctional dependency between the attributes is represented as X->Y, which specifies Y is functionally dependent on X.
