Two data centers used for retail credit authorization are located in two different major population centers, which are separated from each other by a large zone of very little population. Each data center is intended to cover a particular geographical area and thus contains data that reflect the account status of the card holders in that area $($only$).$ Terminals for each area are connected to the corresponding data center. Communication between both data centers ocurrs only in case a card holder from one geographical area shops in a retail credit establishment of the geographical area covered by the other data center. a$.$Would this approach be suitable if the two major population centers were close to each other? Why or why not?
