SAS Intelligence Storage
SAS has its own data store, called SAS Intelligence Storage. It’s a relational system running on SMP boxes, whose unique feature is that it has fixed-length records and hence is a perfect array, for speedy lookup. This is highly analogous to classical MOLAP systems. However, SAS reports that customers store up to several hundred terabytes of data in SAS Intelligence Storage, which is definitely not very analogous to what goes on in the MOLAP world.
It sounds as if the product is optimized for data mining and generic OLAP alike. Indeed, SAS Intelligence Storage is used to power both SAS’s data mining and other advanced analytics, and also its more conventional BI suite.
