Abstract

Reverse engineering for program understanding is always the first step in a reengineering project. When CASE tools are used to develop legacy applications, there are hidden assets that are not usually available. These assets may be very useful for program understanding because they contain design and architectural information usually only found, if at all, in the applications' documentation or are implicit in the code. Reverse engineering this type of applications requires taking advantage of these assets. In this paper, we describe a case study in which we reverse engineer a large legacy application which was constructed using SNAP, a CASE tool for the AS400. By exploiting vital information generated by SNAP, we were able to obtain representations of the application's persistent data and of dependency information of programs that make up the application. This experience led to the definition of guidelines that can be used to tackle the problem of reengineering applications that were developed with CASE tools.
理解CASE生成的遗留应用程序:一个案例研究
理解程序的逆向工程总是再工程项目的第一步。当使用CASE工具开发遗留应用程序时,存在一些通常不可用的隐藏资产。这些资产可能对程序理解非常有用,因为它们包含设计和体系结构信息,如果有的话,通常只能在应用程序文档中找到,或者隐藏在代码中。逆向工程这种类型的应用程序需要利用这些资产。在本文中,我们描述了一个案例研究,在这个案例研究中,我们对一个大型遗留应用程序进行了逆向工程,该应用程序是使用SNAP (AS400的case工具)构建的。通过利用SNAP生成的重要信息,我们能够获得应用程序持久数据的表示以及组成应用程序的程序的依赖信息。这种经验导致了指导方针的定义,这些指导方针可用于处理用CASE工具开发的再工程应用程序的问题。
