Yep, that was my interpretation of the question too. But I wouldn't have put down the document or key/value stores so harshly, since they do have their uses, even outside of high-scalability scenarios. As for BerkeleyDB and the rest: I'm not too familiar with them, but my impression before was that querying them wasn't as elegant as it is with some of the recent key/value or document stores. Probably that's the reason these new things receive such a hype: they do have something for them, even if the hype makes those bigger than they really are.
