The significant functional differentiation of Neo4j in the retail space is the ability to quickly traverse interconnected datasets and make recommendations in “real time”.  Competing approaches require large batch processing activities done offline to compute recommendations against large aggregate datasets, usually as nightly routines.  Others attempt to parameterize or profile products and users, leaving the connection of interests and products simply to keyword matching and categorization. These methods produce results that can quickly become stale and outdated if they are not done frequently and lack flexibility and capabilities to dynamically change .
