| | Universal Relation Assumption | |
| It postulate that exists a Relation that contains all the others Relations (so the name of Universal).
That implies different attributes must have different names and the same attribute must have the same name in every relation it's present.
It's very useful in the normalization process.
See A Simplified Universal Relation Assumption and Its Properties for the original paper on the subject.
