I understand why all accumulated transactions have to be processed in the correct sequence if they are batched up daily, but why is an individual transaction not instantaneously and permanently processed with the results being committed right then? Why is it necessary to run huge batches of transactions at night? I am guessing that committing the transaction instantly would take too long for the average customer's patience when standing at an outdoors ATM in the rain. Are there any other reasons? When I buy an airplane ticket online, I get my whole transaction complete in one sitting and do not have to wait until the next day to receive confirmation of my reservation, but it always takes several minutes to do it online.
