A Methodology for Developing Distributed Programs

Abstract

A methodology, different from the existing ones, for constructing distributed programs is presented. It is based on the well-known idea of developing distributed programs via synchronous and centralized programs. The distinguishing features of the methodology are: 1) specification include process structure information and distributed programs are developed taking this information into account, 2) a new class of programs, called PPSA's, is used in the development process, and 3) a transformational approach is suggested to solve the problems inherent in the method of developing distributed programs through synchronous and centralized programs. The methodology is illustrated with an example.
