The NoSQL buzzword caught fire just a few short years ago, but we're already well into the second generation of the movement. While the early stacks of code were just experiments, the systems today are much more mature, ready for action, and facing the hard truths of a technology that's come of age - so much so that some of the best NoSQL data stores have already been rewritten, and a few are even sticking the 2.0 label on the latest version. Here's a list of some of the better-known tools for building fast, scalable repositories for lots of data.
Most NoSQL databases store flexible bundles of keys and values. Neo4J stores relationships between objects, a structure that mathematicians often confusingly call a "graph." The tool includes a number of algorithms for searching and analyzing the relationships, making it possible to look for someone who is a friend of a friend of a friend. These "graph traversal" algorithms save you the trouble of chasing pointers.
