I sure can, but you should probably refer to your textbook and lessons for these things.

I outlined the section on relationships and I understand One to One, One to Many, and Many to Many.

Does the n stand for many?

Also what does identifying or non-identifying relationship mean?

Yes, n represents many.
Identity deals with the relationship using an identity reference. I.e. A parent table is required.


A search for "identifying vs non-identifying relationship" it provides examples to clarify the explanation.....
