Question regarding BCNF Normalization
I came across a statement that says that in BCNF, a prime attribute cannot be transitively dependent on a key. But consider a relation R (A, B, C) where, A --> ABC , B --> ABC , C --> ABC Clearly it is in BCNF and each of A ... > C . Thus, we can tell C(a prime attribute) is transitively dependent on A (a candidate key) !! Where am I making mistake?
