Most clients I've talked to about this, even before getting into the nitty-gritty of these issues, don't WANT multiple users to be able to make changes to the same customer/order/whatever at the same time. As a matter of fact, some customers have actually demanded an approach that follows the pessimistic rule.Well if customers *demand* a pessimistic scenario, you need to implement one. ;-) I'm not sure I'd allow that to dictate behavior for every customer, though.
Just curious- what sort of customer demands pessimistic locking?
"... They ne'er cared for us
yet: suffer us to famish, and their store-houses
crammed with grain; make edicts for usury, to
support usurers; repeal daily any wholesome act
established against the rich, and provide more
piercing statutes daily, to chain up and restrain
the poor. If the wars eat us not up, they will; and
there's all the love they bear us."
-- Shakespeare: Coriolanus, Act 1, scene 1
