Complex databases can be understood well with visual representation. A graph is a very intuitive and rational structure to visually represent such databases. The graph data model proposed in this treatise formalizes data representation and operations on the data in terms of the graph concept. In this model, a database is defined by a schema graph where nodes represent record types and arcs represent link types that are relationships between two record types. The capabilities of the model include direct representation of many-to-many relationships and of the relationships within a single record type.
