Abstract

This paper presents a new approach to the use of design patterns for the reengineering of legacy code, using a mapping from procedural design patterns to object-oriented patterns. We show also how object-oriented design patterns can be formalised and correctness conditions for their application derived, in order to justify the preservation of functionality in the reengineering process. We conclude with a case study of reengineering of a legacy COBOL application.

使用设计模式重新设计遗留应用程序

本文提出了一种使用设计模式对遗留代码进行再工程的新方法，使用从过程设计模式到面向对象模式的映射。我们还展示了如何将面向对象的设计模式形式化，并为其应用程序派生出正确性条件，以证明在再造过程中保留功能是合理的。我们以一个对遗留COBOL应用程序进行再工程的案例研究作为总结。
