Question
A set of FDs for the relation R{A, B, C, D, E, F} is AB →C, C → A, BC → D,ACD → B, BE → C, EC → FA, CF → BD, D→ E. Find a minimum cover forth is set of FD
Solution
To find a minimum cover for the given set of functional dependencies (FDs), we need to follow three steps:
- Step 1: Left Reduction In this step, we try to remove extraneous attributes from the left-hand side of each FD. An attribute is extraneous
