The Data Complexity of Consistent Query Answering for Self-Join-Free Conjunctive Queries Under Primary Key Constraints
Summary: Effective complexity classification of CERTAINTY(q) for self-join-free Boolean conjunctive queries under primary-key constraints: FO-membership decidable and an effective P vs coNP-complete dichotomy. Settles a decade-old open problem by combining and extending prior techniques.
