The vertices are sometimes also referred to as nodes and the edges are lines or arcs that connect any two nodes in the graph. More formally a Graph is composed of a set of vertices ( V ) and a set of edges ( E ). The graph is denoted by G (V, E). WebA graph database ( GDB) is a database that uses graph structures for semantic queries with nodes, edges, and properties to represent and store data.
