【Abstract】 the article is on development and practice for the country railway items.Information flow ofsystem engineering’s concept is Introduced Into MIS. There are several factor for interfering and condition the information flow expressed ,it are what we have to take into formulation.From boundary face prototyping approach,we formulate several doing method and consideration in the structured system design of information flow.The fall article introduced a development method of MIS.更多还原
