Data Exchange and Incomplete Information

Summary: Identifies that data-exchange anomalies arise from mishandling incomplete information and neglecting open/closed-world distinctions. Proposes CWA-based target solutions (extremes: universal and core), null-aware query semantics removing anomalies, plus complexity and maybe-answer results. (summarized by gpt-5-mini on Feb 09 2026)
