I agree that that is the point, and full credit to them for going down this route, it's certainly innovative and targeted at an area that promises real business benefit. I still don't see how this approach will deal with the typical app I see today with code and objects in the db, code and objects on the middle tier in Java (upgrading that online could be a challenge) and with code and objects residing on the (thin) client in the form of javascript/cookies/cached .jars/dlls etc. Of course also most apps I see (excluding e-business suite) are database agnostic as well and so likely will not care about editions anyway.
Were the typical application these days one with the code in pl/sql/views in the db and a simple presentation layer then maybe, certainly APEX based apps as an example might well become online upgradeable quite quickly. Anyway we shall see. It's a grand vision and I applaud that, but as a somewhat sceptical dba I have my doubts as well.
Cheers
Niall
