My point is that a lot of data in the real world is not normalized. Simple stuff like "branding" and "manufacturer." In a normalized world, you update the name of a product, and all units are magically updated. In a materialized world, they are what they were when they shipped. We may pencil over updates, but that has to be done on each "row," as it were.
