The design of PLAIN
Anthony I. Wasserman · 1980
The successful construction of medium and large software systems requires the management of the complexity inherent in the problem being programmed. A well-disciplined approach to software development involves the production of a complete specification, a complete problem solution, and program design prior to the inception of actual coding. In practice, this requires the production of some form of program design representation [1] from the original specification, with the action of each module specified with a program design language [2]. Furthermore, data structures are specified and refined, in some cases to physical data structures, but more commonly to logical data structures.
