Yeah, I suppose so ... if all they're doing is reporting on a static set of
data which is not transactional ... sure. If it's a disposable,
limited-time-use application.

However, I have yet to see in my professional experience any application that
was really this way and stayed this way once it was in use ... relations have
a way of creeping in, and planning for them is less messy than refactoring.
