A general model of systems consisting of "control units" and "passive units" is established. These units could be instructions and data in computer programs, for example, or information processing modules and files in data management systems; other applications are also suggested. The model contains both structural and behavioral information. The sets of units of the model are partitioned, and the resulting subsets correspond to different groups of elements of real systems.
Boundary crossing, computer network, data management, information retrieval, information system model, paged system, partitioned system, segmented program, virtual memory.
