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 are connected to the corresponding data center. Communication between
both data centers occurs 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.

b) Classify the relationship between both data centers as
