Counting Database Repairs Entailing a Query: The Case of Functional Dependencies
Summary: Extends the FP/#P-complete dichotomy for counting repairs that entail a self-join-free CQ from primary keys to general functional dependencies, characterizing exact data complexity. Shows counting can be inapproximable under FDs, but FDs with a left-hand-side chain admit an FPRAS (an island of approximability). (summarized by gpt-5-mini on Feb 09 2026)
