Temporal Database and its Relational Algebra

[WWGD]

Hi all,
Just curious on whether temporal databases are designed in the same way as "standard" relational databases,
so that queries on temporal databases are wffs in temporal logic , i.e., using Until, Release and all other unary
operators , and the query outputs is the set of models for the wff? Thanks.

There are wff's from spatial relations resultsets for spatial databases. I have never worked in a temporal db environment. I do not know.
