Rational Data Base Standards: An Examination of the 1978 CODASYL DDLC Report.

Abstract

The CODASYL DDLC 1978 Report incorporates numerous enhancements and language changes. Unfortunately, the major design limitations associated with earlier reports and specifications, in particular a schema facility too closely related to machine rather than enterprise requirements and an extremely limited subschema facility, are retained. We suggest that the recent CODASYL specifications remain inappropriate as either an instance of an ANSI/SPARC three-schema architecture or as a candidate for a national data base system standard.
