It depends.

"how do you assure that structure with the information stored within
a database?"

That's another option, but this can't be answered w/o knowledge of
a use-case.  One nifty thing you may want to look into *if* you go
with the "calculation within database" solution would be pl/R, which
should enable you to output postscript graphs of your results as
a report ....
