What is Neo4j?

Neo4j is a graph database that stores data in a graph. Data is stored as Full definition for node (opens in a new tab)A vertex in a graph. In a property graph it can carry labels and properties. and Full definition for relationship (opens in a new tab)A named, directed connection between two nodes. Every relationship has a type, a start node and an end node. instead of tables or documents.

Graph databases are particularly useful when the connections between data are as important as the data itself.
