Use when reasoning about the foundational theory beneath data modeling: Codd's relational model (1970) and the algebra it sits on, the normal forms (1NF, 2NF, 3NF, BCNF, 4NF, 5NF) as a precise sequence of constraint-elimination steps, functional dependencies and the closure algorithm, Chen's entity-relationship model (1976) as a higher-abstraction layer above relations, the principled case for and against denormalization, the relational-vs-document tradeoff at the conceptual level, the immutable-data-model alternative (event sourcing, append-only tables), and the historical and theoretical literature that grounds modern database design. Do NOT use for practical persistence design and method (use data-modeling), for safely applying changes to an existing schema (use schema-evolution), for choosing what indexes to maintain (use indexing-strategy), or for the conceptual-modeling layer above the data model (use conceptual-modeling).
