Abstract : The paper presents a tool for describing the Army Information and Data System in fundamental terms: mathematical model based on event chaining. Event chaining describes the connective properties of an information network by relating reports in the network to the stations producing and receiving them. The term 'report' is used simply as a generic term for a grouping of data that is treated as a unit. The formal mechanism describing the relations among reports and stations is called a 'sequence table.' The sequence table is a convenient means of describing the pattern of data flow in a network. The information that it presents is essentially the same as that given by a systems flow chart. However, it has several advantages that a systems flow chart does not possess. First it is analytic rather than graphical. This permits it to be stored in a computer and manipulated by mathematical rules and formulas. Second it can be constructed automatically from a list of the inputs and outputs, together with their addresses, of the stations comprising the network. This permits it to be synthesized from information available at the stations without the necessity of having a systems flow chart in advance (the event-chaining process). And third it provides a convenient frame work on which to hang extensions describing other attributes of the information network.
