In an installation having a number of point-of-sale terminals it is common to provide one terminal with additional computing and storage capacity so that it can function as a controller for the entire cluster. Ideally, each terminal in a cluster would have price data on all the merchandise so that any sale can be handled with the need to communicate with another, larger, terminal or controller. This is costly, and the alternative, placing all data in a single storage which is remote from the terminals, is too slow and unreliable.
