'Intended as a tutorial text on one approach to data base management, namely that espoused by the CODASYL organization between 1967 and 1971 and perpetuated in the numerous reports published by CODASYL between 1968 and 1975. There are several commercial implementations of this approach available, best known of which are Univac's DMS 1100; Honeywell's IDS/2; Cullinane's IDMS available on IBM machines and also on ICL machines; and Siemens' UDS.
