Getting Unique Solution in Data Exchange
Summary: Extends schema mappings to guarantee a unique target instance, enabling query answering for arbitrary (including non-conjunctive) queries. Recasts this as definability abduction and identifies minimal relational mappings under a semantic minimality criterion. (summarized by gpt-5.6-luna on Jul 24 2026)
