I am not sure the two are related because temporal data is time interval arithmetic while Time Series is relational calculus but I could be wrong so I have found the best Temporal book it is free download it and let us know.

Heh... only every other Tuesday. Tongue

What is the basis of your Bi-Temporal design?

--Jeff Moden

RBAR is pronounced ree-bar and is a Modenism for Row-By-Agonizing-Row.
First step towards the paradigm shift of writing Set Based code:
Stop thinking about what you want to do to a row... think, instead, of what you want to do to a column.
If you think its expensive to hire a professional to do the job, wait until you hire an amateur. -- Red Adair

I expect you are referring to Kimball's "Dimensional Modeling" patterns. The concepts described by Kimball are fairly unsophisticated and limited in their application. There are much better sources on temporal modeling problems such as the Snodgrass book already mentioned or the Date, Darwen and Lorentzos' book:
