A B C 1 2 2 2 7 1 1 3 7 5 8 3 Given the above relation: 1. Please identify 6 functional dependencies

Answer 1

Answer #1

Functional Dependency:

It is a relationship between two attributes in which the right-hand side attribute is functionally dependent on the left-hand side attribute.

If the value of attribute Y is determined by the value of X then it is represented as given below:

X → Y

The functional dependencies in the given relation are:

B -> A

A -> B

C -> A

C -> B

BC -> A

AC -> B
