Software on Demand: Issues for RE

2. A base application. The example chosen was an information system for the University of Oregon campus. The base system, which could be given away free or at low cost, provided a map of campus and window panes for new components to work within. The expectation is that the base application would run on a user’s home computer. The user would ask (demand) new components on an as-needed basis, e.g., if the user wanted information on computer labs on campus, she would ask for a specialized component to be added to the base app. The base application was written in Tcl/Tk for WIN95.
