I was thinking that same thing a while back. I could see where an application might not enforce the same RI that a backend would. Say, for example an application is looking at a subset of information that doesn't include a child entity. The application wouldn't even KNOW about the relationship, much less be able to manage the RI. But the backend might well enforce it.

I too am struggling with trying to say what I mean...plus I'm just trying to consider different scenarios.........
