基于COM原理的进程结构图呈现技术

s for Object-Oriented system with characteristics of distribution and concurrency, extraction and representation of creating relations and communication relations among processes can help users to comprehend target system in the view of high-level architecture. After the analysis of principles of Rational Rose extensibility, a kind of representation technology of Process Structure Graph (PSG), which can reflect creating relations and communication relations among processes, is presented in this paper. PSG is directly represented in the environment of Rational Rose by extending stereotypes of Rational Rose. Finally, a software system with features of distribution and concurrency is used as testing case to verify the validity of this representation technology.
