This article describes a store system in which the price look-up memory is partitioned among point-of-sale terminals connected in a local area network. Price look-up requests go directly from an originating terminal to the terminal having the partitioned price look-up memory for the item identified in the request. In a conventional store system, a single price look-up memory exists in a store controller, to which several terminals are connected. Each time a price look-up request is generated at a terminal, that request must be answered by the store controller. If several terminals in the conventional system generate price look-up requests simultaneously, the store controller must "stack" those requests. Under high traffic conditions, a request near the bottom of the stack may not be serviced for an unacceptably long time.
