A graph database is a database that uses graph structure with nodes, edges, and properties to represent and store data. By definition, a graph database is any storage system that provides index-free adjacency. This means that every element contains a direct pointer to its adjacent element and no index lookup are necessary. General graph databases that can store any graph are distinct from specialized graph databases such as triple stores and network database. Graph databases are based on graph theory. Graph databases employ nodes, properties, and edges.
