On The Semantics Of The Relational Data Model

Summary: Proposes a semantic data model that extends the relational paradigm to capture real-world object types, relationships, and meaningful modification units beyond algebraic constraints. It defines independent object types with insertion/deletion semantics for 3NF relations and analyzes functional dependencies to refine normalization. (summarized by gpt-5-nano on Feb 09 2026)
