As companies like Facebook and Google have introduced us to Graph Search and the Knowledge Graph, developers are learning the benefits of graph database architectures. Graph databases, like Neo4j, have increased in popularity by nearly 250% from last year - the highest among all other DBMS categories, according to db-engines.com. Join Kenny Bastani as we look at the benefits of using a graph database, tour the Neo4j browser, and explore the graphDB community community including available language drivers. Kenny will also walkthrough creating a movie recommendation app on Neo4j 2.0 with an introduction to the Cypher Query Language.
