This paper covers large-scale analytic data marts and warehouses. That is, environments where there is a substantial requirement for complex and/or unpredictable queries but not things like master data management or operational BI (or only to a limited extent). A number of vendors that appeared in the two smaller scale analytic papers do not appear in this update. In some cases this is because they do not physically have the ability to scale to 50Tb but in others it may simply be that they have not demonstrated that capability even if they have the theoretical ability to do so. An example is 1010Data. Another is Microsoft. In this case the company does, in fact, have one implementation of 55Tb but this only just creeps over our limit and the company would accept that its current sweet spot (until the release of Madison) is within the small and medium-sized markets.
