Both, I guess. Each database is one of our clients, and each of those databases can have a range of 50 to 300 users at any given time, mostly querying and updating the same tables.
It’s a call center / dialing system. Most of the operation consists on the operator querying for a customer to place a call. Once found, the record is locked with that operator until the call ends.
So we have many users in a race condition on the same table.
