Abstract
An enterprise information system in which personal work stations, personal data bases which are held in the work stations, a processor only for use in a division, and intradivision data and interdivision data which are held in the processor are provided. An informal communication path directly connects the work stations in an enterprise among the divisions and an intradivision formal communication path mutually connects the work station in the division to the processor to hold the intradivision data base or the interdivision data base corresponding to the division or both of them. An interdivision formal communication path mutually connects the processors to hold the interdivision data bases. The intradivision data base can only be accessed by the intradivision formal communication path of the division.
