WebAug 24, 2011 · A graph database's main data elements are nodes and edges. An object database does not have the notion of a (bidirectional) edge between two things with automatic referential integrity etc. A graph database does not have the notion of a pointer that can be NULL. (Of course one can imagine hybrids.) Webgraph database: A graph database, also called a graph-oriented database, is a type of NoSQL database that uses graph theory to store, map and query relationships.
