摘要: Current reverse engineering technology is typically based on program analysis methods such as parsing and data flow analysis. As such, it limited in what can accomplish. Knowledge of the application domain containing a help overcome this limit aid comprehension process. The paper discusses relationship engineering. Two case studies are presented. first describes how knowledge, expressed an object-oriented framework, process for well-understood domain. second be used to build model. Issues raised by confluence discussed, implications future work area suggested. >
