First I am not a full-time consultant and there are far more proficient people who post on here than myself. Second, while I appreciate the time invested in responses in this thread, I would also appreciate it if you do not second guess my opinions when promoting a personal agenda (whatever its merits may or may not be) with another poster.

I would (personally) not be satisfied with a model that exonerates itself of responsibility for representing constraints (which are equally propositions we are trying to model after all) to the querying application. I _am_ open to exploring tangential ideas from other systems, but am not willing to lightly abandon the mathematical rigour that the RM offers as a data model, especially in its supporting algebra.

Anyhow, my interest here is purely to consider how one might maximise query preservence in an environment where schemas change frequently. Thank you to those who have spent time offering their opinions so far. Received on Sat Apr 15 2006 - 01:37:12 CEST
