Size still isn't everything
Giant data warehouses certainly benefit storage vendors, hardware vendors, consultants who build and tune them and DBAs, who love to discuss their largest database as if is was a proxy for their, er, masculinity (apologies to those female DBAs out there, but you know what I mean; it is good for your resume to have worked on very large databases). The trouble is that high volumes of data make it harder to quickly analyse data in a meaninfgul way, and in most cases this sort of data warehouse elephantitis can be avoided by careful consideration of the use cases,probably saving a lot of money to boot. Of course that would involve IT people actually talking to he business users, I won't be holding my breath for this more thoughtful approach to take off as a trend. Well done Madan for another thoughtful article.
