Talk:Elementary key normal form

Definition of "Elementary Key"

Would be nice to have a definition of elementary key mentioned in the page.

Also for "elementary functional dependency". I had to go through Citation [1] to get the definition;

here it is from the source:

Say that G denotes a set of FDs and that f: X -> A is an element of G. Then f will be said to be elementary with respect to G, when A is not in X and G+ does not contain an FD, X’ -> A, with X’ C X.

I still don't know what an "elementary key" is. Scorbiclife (talk) 09:01, 17 February 2023 (UTC)

I am sorry, I don't know why I could not find the exact definitions on the page. Scorbiclife (talk) 07:28, 20 February 2023 (UTC)

I have included an example of an elementary key in the example table I provided. I hope this is sufficient. TheChairAndKeyboard (talk) 15:57, 18 July 2025 (UTC)
