Abstract: A data base management system is disclosed in which data entities are records representing nodes in an entity-relationship directed graph. The body of each node represents one of the physical entities to be utilized while the edges of each node represent relationships between that physical entity and other physical entities. Some of the edges are hyperedges to permit the identification of simultaneous relationships with more than one other node. An application of this system to the assignment of telephone outside plant equipment to telephone subscribers is also described.
