Neo4j provides drivers which allow you to make a connection to the database and develop applications which create, read, update, and delete information from the graph.

Nodes are the entities in the graph.

• Nodes can be tagged with labels, representing their different roles in your domain. (For example, Person).
• Nodes can hold any number of key-value pairs, or properties. (For example, name)
• Node labels may also attach metadata (such as index or constraint information) to certain nodes.

Relationships provide directed, named, connections between two node entities (e.g. Person LOVES Person).

• Relationships always have a direction, a type, a start node, and an end node, and they can have properties, just like nodes.
• Nodes can have any number or type of relationships without sacrificing performance.
• Although relationships are always directed, they can be navigated efficiently in any direction.
