On the Decomposition of Join Dependencies

Summary: Hypergraph-based decomposition methodology for join dependencies using the notion of “hinges” to separate cyclic/acyclic parts and simplify analysis and integrity checking. Defines the class of unambiguous JDs—exactly those with a unique decomposition obtainable by their method—and proves uniqueness via a modified chase plus a structural characterization.
