Try customer bases with millions of users making changes to their accounts
(either passively by using their accounts or actively through a CSR or customer
account self management).
This might include a customers session count, billing preferences, CoS
categories, geographic info. And whatever else you can think of. This goes
for service offerings such as plain old dial-up access, VoX (X=IP,ATM,FR) or
whatever else, such a E911 info to be fed back into an IP/SS7 SCP.
I am scared of keeping real time account info in it because this will take away
transaction cycles from other (more vital?) tasks, with the concern that by
the time the real time info actually propagates, it no longer is real time.
Cheers,
Chris
