Hi TECHTUD! Brilliant explanation but i am confused. Why is A a NON prime attribute. Closer of CEA will get you all attributes. Doesnt this make CEA a candidate key? If thats the case shouldnt A also be a prime attribute?

Sir...
What about non prime attributes in such case..
We have a relation (A B C D) and from that relation, let us consider to that we got C.K as AD, BD, CD and now prime attributes are ABCD ..

I m just confused with those functional dependency and CK...
