A data base management system according to the invention stores, retrieves, and modifies data records within a digital computer data base, permitting access to related data records through partnerships joining record pairs. Partnership sets are employed to relate data records on a one-to-one, one-to-many, and a many-to-many basis. The invention facilitates the modelling of real world structures and events in a data base whose logical representation closely depicts those structures and events.
