Abstract
Although central to the current direction of dependency theory, the assumption of a universal relation is incompatible with some aspects of relational database theory and practice. Furthermore, the universal relation is itself ill defined in some important ways. And, under the universal relation assumption, the decomposition approach to database design becomes virtually indistinguishable from the synthetic approach.Keywords
