There are now several data base management systems which are based on the proposed CODASYL specifications1, 2; these include UNIVAC's DMS 11003, DIGITAL EQUIPMENT's DBMS-104, Cullinane's IDMS5, and to some degree Burroughs' B6700 DMS6. Since the CODASYL specifications are still not yet finalized, and since many important features of the proposed standard are left as "implementor defined", these particular systems all differ in a number of respects. However, their basic data structuring capabilities remain similar. The purpose of this paper is to outline some data base design considerations when using the CODASYL class systems, and to highlight differences with other types of systems.
