What I also haven't mentioned yet is the query language itself.  Neo4J
uses the Cypher query language (yes - due to the names I suspect all the
founders loved the movie "The Matrix").  The Cypher query language is
really good at making the types of queries that Computational Intelligence
researchers typically need to make.    (03)

³Cypher² is a declarative graph query language that allows for expressive
and efficient querying of the graph store without having to write
traversals through the graph structure in code.  YOu guys know I don't
often rave about technology so this should be a hint that something cool
is brewing from the smart folks at Neo Technologies.    (04)
