There are 2 methods of handling history. The preferred method is to store
the elements of the historical calculation and recalculate in a query. The
other method is to store the results of the calculation and subsequently
query those. Storing the elements also allows other calculations based upon
those elements and more closely follows database relational set theory and
normalization rules.
