I've spent the past few weeks here at work researching and playing with NoSQL databases (and especially MongoDB) for a new feature we're developing that doesn't easily fit into a relational model. And so far, I really like what I see.

He also mentions that object databases, unlike their true NoSQL cousins, "missed the boat" and haven't caught on quite as well. The reason he suggests? Their language-specificity hinders them from being more widely adopted than a cross-platform, cross-language tool. NoSQL databases are here to stay and are already finding their way into major applications all over the web and represent a strong alternative to the typical relational database storage methods.
