Any reason?? 0 votes 0 votes DebRC commented Dec 1, 2022 reply Follow Share When an attribute ‘x’ determines a prime attribute ‘B’ you can actually replace that prime attribute ‘B’ in any Candidate Key ($AB$) it is in with ‘$x$’ (CK will be $Ax$). Think about it, ‘$x$’ will ultimately determine ‘$B$’, thus making ‘$Ax$’ also a candidate key. 6 votes 6 votes Shoto commented Dec 1, 2022 reply Follow Share @DebSujit yes right, got it now👍 1 votes 1 votes JAINchiNMay commented Dec 1, 2022 reply Follow Share Thanks buddy 1 votes 1 votes Please log in or register to add a comment.
