            ..

    Inherit from this package and you can make a resultset class from a
    view, but that's more than a little bit misleading: the result is
    transparently writable.

    This is accomplished through the use of stored procedures that map
    changes written to the view to changes to the underlying concrete
    tables.

WHY?
    In many applications, many classes are subclasses of others. Let's say
    you have this schema:

        # Conceptual domain model

Inherit from this package and you can make a resultset class from a view, but
that's more than a little bit misleading: the result is B<transparently
writable>.

This is accomplished through the use of stored procedures that map changes
written to the view to changes to the underlying concrete tables.
