Obtaining Complete Answers from Incomplete Databases

Summary: Query answering over incomplete databases; a complete algorithm for answer-completeness via query-update independence. Identifies a polynomial-time case for conjunctions of comparisons; state completeness and extensions to partially-incorrect data. (summarized by gpt-5-nano on Feb 09 2026)
