Neo4j has been named as a 2015 Technology of the year by InfoWorld, highlighting its growth and success in strengthening its product, community, and personnel. The graph database is known for its scalability, with a learning curve short enough to tackle tasks from small to large, while maintaining ACID-compliance and two-phase commit transaction support. Its API allows modification of shortest path algorithms, and a declarative query language called Cypher provides an alternative to SQL. Neo4j offers both free open source and enterprise editions, with additional features such as clustering, caching, backups, and monitoring capabilities available in the latter. The company's online documentation is highly regarded for its interactive nature, allowing users to explore graph database concepts and execute code against a temporary database.
