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.
