Coping with Incomplete Data: Recent Advances
Summary: Surveys advances reconciling theoretical "certain answers" with practical query evaluation for incomplete data: refines the notion of certainty, identifies tractable cases, and provides deterministic and probabilistic approximation schemes. Evaluates correctness and necessity of SQL's three-valued logic for producing query answers. (summarized by gpt-5-mini on Feb 09 2026)
