On Equivalences of Database Schemes

Summary: Shows natural equivalence equals fixpoint equivalence for database schemas without any restriction on constraints, proving the weaker-seeming notion already captures the full semantics. For schemas with functional dependencies, gives a compact syntactic characterization of natural equivalence. (summarized by gpt-5-mini on Feb 09 2026)
