IBM Labs Perspective on Neo4j
Ajit Koti, a software developer at IBM Labs in Bengaluru, India, has written a great presentation on his experience with 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.
