Conformed facts
In addition to conformed dimensions, you need conformed
facts. Conforming a fact really amounts to standardizing the definitions of
terms across individual marts. Often, different divisions or departments use
the same term in different ways. Does “revenue” refer to “gross revenue” or
“adjusted revenue”? Does “units shipped” refer to cases of
items or individual items?
Make certain your design team
develops, early on, a uniform enterprise taxonomy—and enforce it.
