I'm trying to wrap my head around the identifying/non-identifying relationships in Crow's Foot notation. I have read in most places that an identifying relationship means that the FK is a part of the entity's PK. However, wouldn't that be the same as simply having the FK be non-null and not include it in the primary key?
To me this is an identifying relationship, since a Student cannot exist without a University. Though, I do not have plans on including the FK from Student to University in the Student's PK.
