It includes BD-->F, hence it is redundant. 0 votes 0 votes amitqy commented Oct 1, 2018 reply Follow Share To remove B from BD-->F we have to see if D alone can determine B, then B is redundant. I am unable to find how D alone can determine B 0 votes 0 votes Vikas Verma commented Oct 1, 2018 reply Follow Share Look at it like this: D-->F means BD -->BF which is BD-->F and BD -->B 0 votes 0 votes Vikas Verma commented Oct 1, 2018 reply Follow Share In the procedure of deriving minimal cover, there are two steps 1. Remove redundant attributes 2. Remove redundant dependencies What you're trying to do is only step one. But in reality that dependency would be removed during step 2. 0 votes 0 votes Please log in or register to add a comment.
