Duplicate database would be rows of a repeating table? Or would it be something more complex? , this question fits into the context of database relations

  • It depends on the exact context where the word is being used. It could be that, but it could be something else. For me the question is not clear and an answer will be a kick for lack of context.

Definition of Duplicate:

Any object, written etc. of representation or function identical to that of another; copying, copying. - Google

I believe you are referring to tuples, starting from your previous question, if not ignore this answer:

The body of a database relationship is a set; we know that in mathematical sets are not ordered (this means that the elements are all distinct).

Note: A relation and a table are not the same thing because a table can contain duplicated rows, while a relation, for definition, never contains any tuples in duplicate. - Adapted by: Vítor Subhi
