First-Order Rewritability in Consistent Query Answering with Respect to Multiple Keys
Summary: Extends consistent query answering under key dependencies to schemas allowing multiple keys per relation, focusing on self-join-free Boolean conjunctive queries. Proves decidability of FO-rewritability and provides an effective procedure to construct an FO rewriting when one exists. (summarized by gpt-5-mini on Feb 09 2026)
