When I read how relational databases are inadequate to store, index and process unstructured data in real time, it made me draw an analogy between the old virus/anti-virus game where it was a race between the virus writers and the anti-virus software makers, and sometimes they were accused of being in cahoots. Could we not say the same thing about the content indexing technologies (NoSql, MapReduce) and the content creating technologies (Twitter, ECommerce, Content Farms)?
