Discovering Denial Constraints
Summary: Proposes Denial Constraints (DCs) as a more expressive integrity-constraint language than FDs/CFDs, with sound inference rules and a linear-time implication test. Devotes an instance-driven DC discovery algorithm and a novel scoring function to rank candidates for user validation; empirical evaluation on real and synthetic data demonstrates scalable, effective constraint discovery.
