True, and often the views can be restricted to insert only data that
will be 
visible using this view.

This seems to be a little more complicated that Tom described (I.e. it
has 
probably more than one relation involved or uses a function to get
CURRENT_USER's 
department id)

IIRC MS Access has much broader repertoire of updatable views than
described 
by Tom. Can be it's an extension to standard SQL though.
