Heineman，计算机科学系，WPI 遗留系统是任何正在使用并且必须演进的软件系统 以满足不断变化的条件。这些系统必须重新设计 因为随着时间的推移， 每一次的保养。拟议的研究结合了 功能和软件组件的概念， 从遗留系统中提取基于特征的软件组件 系统首先，引出目标遗留系统的特征 并使用现有的代码分析工具， 这些特征被识别。这项任务是由 回归测试套件，许多遗留系统已经有，以确保 随着系统的不断升级， 第二，软件 组件是从遗留系统重构的。简言之，数据 为了进化的目的，分析由执行跟踪生成的数据。 这项研究将为一个可行的长期战略提供一个 组织逐步现代化其软件代码库。一 将界定和应用重新设计方法。一 相应的成本/节约模式将根据以下因素制定 财务系统遗留系统的初步成功 公司该方法将被打包和传播，以确保 拥有遗留系统的其他组织可以轻松地从 这项研究的结果。

Proposal Number: 0220166 Title: ITR/SY Features, Components, and Legacy Systems PI: George T. Heineman, Computer Science Department, WPI A legacy system is any software system that is in use and must evolve to meet changing conditions. These systems must be re-engineered because over time, the ability to evolve the system decreases with each successive maintenance. The proposed research combines the concepts of features and software components in a novel way to extract feature-based software components from a legacy system. First, the features of the target legacy system are elicited and using existing code profiling tools, the code associated with these features is identified. This task is made possible by the regression test suite that many legacy systems already have to ensure proper functioning as the system is upgraded. Second, software components are refactored from the legacy system. In short, the data generated by execution traces is analyzed for evolution purposes. The research will provides a viable long-term strategy for an organization to incrementally modernize its software code base. A reengineering methodology will be defined and applied. A corresponding cost/savings model will be developed based upon preliminary success with the legacy system for a financial company. The methodology will be packaged and disseminated to ensure other organizations with legacy systems can easily benefit from the results of this research.
