:It's not clear from the section, but Date's view is that being in 1NF and being a relation are equivalent, and so "relations" not in 1NF are not relations at all. [[User:Charnel Mouse|Charnel Mouse]] ([[User talk:Charnel Mouse|talk]]) 23:49, 17 May 2025 (UTC)
::Relations as a mathematical structure predate its use in database terminology, so this sounds like a misunderstanding. [[Special:Contributions/80.62.117.169|80.62.117.169]] ([[User talk:80.62.117.169|talk]]) 06:27, 27 May 2025 (UTC)
:It's true that this section should instead contain the Date's definition of 1NF rather than his corollary of 1NF being equivalent to his definition of a relation. And I believe Date's definition is very valuable and should be paid more attention to. He formalized this concept very rigorously.
