I would like to ask for some design advice.

Both Company and Outlet are Hibernate persistent classes.
Whenever a sale is made at the Outlet, we will increase the sale value and counts in tandem for the Outlet. I would like to know how you whether: is it good to also update the totals in Company as well during a sale tx ? In general how do you handle derived totals like this ? In Hibernate, how would you propogate changes like these ?
Regards,
Pho

I'm reading about the MonthEndClosing pattern and it seems like a possible solution. So rather than cascade the totalling up process at the actual moment of sale; it could be done at EOD. What do you think ?
