Relational vocabulary: in a relation, are columns sometimes called “attributes” (the formal term in the relational model)?

Question

Accepted Answer

Introduction / Context:Terminology matters in data modeling. The relational model uses the term “attribute” to refer to what many SQL tools and users call a “column.” This question checks recognition of the formal term. Given Data / Assumptions: We are discussing the relational model, not specific vendor terminology. “Attribute” is the formal name; “column” is the common name. The statement says “sometimes called ‘attributes’,” acknowledging both usages. Concept / Approach:In the relational model: table → relation, row → tuple, column → attribute. Using “attribute” emphasizes that each column draws values from a defined domain (type) and participates in constraints such as keys and dependencies. Step-by-Step Solution: Map everyday terms to formal terms: column → attribute.Confirm that documentation on normalization and dependencies uses “attribute.”Therefore, the statement is correct. Verification / Alternative check:Review any normalization discussion; you will consistently see “attribute” used. Why Other Options Are Wrong: “Incorrect” conflicts with the widely accepted terminology. Mentions of other models or key membership are irrelevant to naming. Common Pitfalls:Thinking that “attribute” and “column” have different meanings; in relational theory they correspond. Final Answer:Correct
