Equivalence and Mapping of Database Schemes

Summary: Introduces JFD-graphs as a formalism for representing Entity–Relationship schemes, with a simple, efficient equivalence test. Characterizes equivalence via complete sets of equivalence-preserving transformations and gives mappings to relational and network schemas. (summarized by gpt-5.6-luna on Jul 24 2026)
