Set usage - Identifier VS. Attribute

[BenziD]

Hi all
we  are having a  little argument in the team

Facts are numeric, usually additive or semi-additive data.
Identifier s  are  all indexed columns or columns containing business keys.
Attributes are typically all other strings.

If I set the non facts as Identifier, dose it make a difference? Does it influence the model in any operational way? :-\

Two of our moderators had an animated discussion on this topic a good while back. Rather than try to reiterate what they were saying, I will simply point you to the post :)

Enjoy!
