To create nodes, relationships, and query Neo4j Database - we need to understand Cypher query language. Relationships will always have direction. Also, a relationship can have properties - example Raman Knows Arun Since 2011. Example - Raman Knows Arun, Arun Knows Alan. To associate or connect nodes we need relationships which tells us how a data record i.e a node is connected to an another node. Properties can be Strings, Numbers or Booleans. So John and Jill have a property ‘plays’ and a value Guitar and Drums respectively, but Jack won't have this property ‘plays’ - this is possible because Neo4j is schema-free. A Node may have zero or more labels.ĭata for a node is stored as Properties, also similar nodes can have different properties - say John plays Guitar and Jill plays Drums and Jack does not play any instruments. Label do not have any properties just a name. Properties - Data Values or Key Value Pairs.Ī Node is a label/name for entities or data record in a graph - an example we can create a Node labeled/named Student, User or Person.You can use Neo4j browser to not only browse your database, explore sample datasets and run queries - you can also use this tool to learn about graph databases and Neo4j.

Once you are in you can access the Neo4j Browser using the default username and password - neo4j. Once the server starts - you are provided with an URL - which you can open in your browser. Based on your OS the installation steps may vary - and once you have a Neo4j application installed - you can now choose the location for the graph database on your computer and start the Neo4j server.

To install Neo4j and run Neo4j Browser - you can head to and download a community or an enterprise edition based on your requirements. Graph Data Model or Graph Data Structure is composed of Nodes and Relationships that connect nodes.Ī query workbench and a visualization interface. It uses Graph Data Model to represent the data, unlike other databases which use tables, documents, etc. 3 min read Introduction to Neo4j - Graph Database.
