Much of the world still hasn’t caught onto graph databases and how they might be used, but the mania around social networking is changing that fast.

In order to capitalize on the moment, Objectivity created InfiniteGraph, an API that sits atop its flagship Objectivity/DB database and turns it into a fully distributed graph database.
