Graph Database

A graph database is a database server that organize data in a network, rather than as tables.

PHP is able to connect to many grpah databases, including: Neo4j, Gremlin, Cassetc.

Graph databases are close to RDF triple stores, which store data as a triplet: origin, destination and link type.
