Getting Unique Solution in Data Exchange
Summary: Extends schema mappings in data exchange to guarantee a unique target instance for each source, addressing multiplicity in query answering. Problem recast as definability abduction, solved by minimal target solutions under a semantic minimality criterion in relational data exchange. (summarized by gpt-5-nano on Feb 09 2026)
