Neo4j is a highly scalable, native graph database purpose-built to leverage not only data but also its relationships. Neo4j's native graph storage and processing engine deliver constant, real-time performance, helping enterprises build intelligent applications to meet today’s evolving data challenges.Neo4j is used by thousands of organizations, including 50+ of the Global 2000, in mission-critical production applications. It's an open source project avalaible on https://neo4j.com/
Available on my github directory with the same name. It's a little java example that show how working with neo4j and graphdatabase. NOTE THAT: Before to execute java project, the neo4j browser client must be on stop.
