Decomposition

Decomposition. Liangsheng Deng Section 2 11/15/2005. Recall Functional Dependencies. A->B holds iff for any pairs of tuples t1 and t2 such that if t1[A] = t2[A], then t1[B] = t2[B]. Armstong’s axioms: Reflexivity rule. If a is a set of attributes and b is a subset of a, then a->b holds.
