Temporal upward compatibility provides a well-defined semantics for every statement S in (nontemporal) SQL-92, when evaluated on the TDBMS and referencing temporal relations.
The only difference in evaluating S in the TDBMS on a nontemporal versus a temporal relation is in the stored state of that relation, that is, a valid-time history is maintained.
It is the responsibility of the TDBMS implementor to ensure that this correspondence is preserved at all times.
