The Revenge Of The Jd
Summary: Establishes equivalence between the universal-relation as a one-relation user view (representative instance) and the ability to answer arbitrary-attribute queries via relational algebra. Characterizes this equivalence by a boundedness condition on schema dependencies and shows that when it holds a finite union of lossless tableau mappings constructs the universal relation.
