I disagree that constraint declaration is programming. The ISO standard vocabulary requires a program to have both declarations and instructions to satisfy some particular task. A constraint declaration is not a program any more than a conceptual analysis is a program.

Applications are programs. Stored procedures are programs. Triggers are programs.

I understand that ODBMSes require one to program in order to enforce integrity because they generally treat integrity enforcement as nothing more than a sub-task in every other task (or method, if you prefer). Received on Fri Aug 31 2001 - 17:03:02 CDT
