We have updateable views if you write the rules for them.
A default updateable view could only be accurate all the
time if it only contained a single table reference.  Our
technique is more flexible and powerful, but scarier due
to RULES being scary.  There are documents on this, however,
and the rules are quite simple if the developer knows what
they want done when the view is updated.
