Gate Question, Year - 2013
I'm still in doubt. You told that we need to check more combination if possible in this question but Candidate Key is nothing but minimal Super Key then if there are other possible then why should I try them? For Example: In your example why should I move to using 3 values (DCH Closure) ? Give any Counter Example to clear my doubt! And Your teaching way is really awesome ! Thanks a lot and keep making more videos.
