- johannes1234321 4y agoMore to "relational algebra" of which joins are a part. (But not necessarily "foreign keys")
- alexvoda 4y agoIndeed. Unfortunately the terminology is so easy to confuse. I have heard the term "relationship" used to describe foreign keys to distinguish it from "relation". But usage is inconsistent and everyone who has heard of "relational databases" but has not heard of "relational algebra" and "relational calculus" will think "relational" refers to foreign keys. Foreign keys are a form of strong typing.
