Abstract

A technique is described whereby a software distributed database program enables multiple stations, using the IBM Personal Computers (PCs) interconnected by means of a local area network (LAN), to function as master/slave inter-relating devices. The software provides different configurations for a station so that any PC in the system may be in a master state or a slave state. Each station is provided with an instruction table describing the station as being the master or slave. At start-up time, the table indicates the specific station as the master and will pass control to a linking software module that will configure the software so that this station has the master environment. All other stations then become the slave stations.
