The traditional direct image system approach consists of having relations constraints implemented at the time when the relation is updated meaning during UPDATE/DELETE/INSERT operations. As a part of a research effort to understand better what may be a relational system implementation, I have discovered that it is actually possible to perform constraint enforcement at constraint declaration time.
Since I have not read anything on the subject, I was wandering and hoping for additional references on that specific aspect. I also woul dlike to know if previous attempts at building such systems have been done in the past. Received on Tue Jun 16 2009 - 09:52:33 CEST
