Rational data base standards: An examination of the 1978 CODASYL DDLC report
1979
Information Systems
Preserved Fulltext
Unfortunately, the major design limitations associated with these earlier specifications, in particular a schema facility too closely related to machine rather than enterprise requirements and an extremely ...
After examination of these limitations, 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 ...
The CODASYL system is not appropriate as an instance of the ANSI/SPARC three-schema architecture. It pre-dates the *ANSI/SPARC proposal and does not successfully capture its philosophy. ...

Rhonda Reese made an earlier version of gcc GC-safe, based on a much earlier approach. That effort convinced me that a source-level approach was interesting, at least in the short-term. ...
