Normalization and axiomatization for numerical dependencies
We show how to use both horizontal and vertical decomposition to normalize a database schema which contains numerical dependencies. We present a finite set of inference rules for numerical dependencies which is a generalization of the Armstrong axioms. We prove that this set is sound and complete for some special cases.
