"Data Mart" == summarized data from a Warehouse used to speed up query times. Main point to a mart is that by pre-aggregating the data the volume (and keyspace) are reduced. Mart's acutally increase total storage becuase they store the data more than once (Warehouse + agg'd into the Mart). Advantage is speed for the 90% of all queries that use agg'd data in the first place. -- Steven Lembark 2930 W.
