    Why is a Concatenated table bad for the RAM consumption compared to Star Schema?

      Hi all,

       

      I was reading QlikView for Developers book and it said in there that a Star Schema is the best type of schema to aim for (something I have read before elsewhere and here).

       

      But I am curious, why is a Concatenated table bad for the RAM consumption compared to Star Schema?
