Abstract :
There is a great demand in industry to migrate from the mainframe to distributed client/server type systems. Three methods of splitting up oversized host application programs with the goal of off-loading them to workstation computers are proposed. The three approaches are by procedural connection, functional decomposition and abstract data typing. Experience in applying each of the methods is described and other measures necessary to downsize a program are explained
