Graph database: Neo4j

Neo4j  is a high-performance, NOSQL graph database with all the features of a mature and robust database. 
The programmer works with an object-oriented, flexible network structure rather than with strict and static tables — yet enjoys all the benefits of a fully transactional, enterprise-strength database. For many applications, Neo4j offers performance improvements on the order of 1000x or more compared to relational DBs.
A graph database stores data in a graph, the most generic of data structures, capable of elegantly representing any kind of data in a highly accessible way. Let’s follow along some graphs, using them to express themselves. We’ll “read” a graph by following arrows arond the diagram to form sentences.
