Abstract
En 中文
Software re-engineering consists of a set of activities intended to restructure a legacy system to a new target system that conforms with hard and soft quality constraints (or non-functional requirements, NFR). This paper presents a framework that allows specific NFR such as performance and maintainability to guide the re-engineering process. Such requirements for the migrant system are modeled using soft-goal interdependency graphs and are associated with specific software transformations. Finally, an evaluation procedure at each transformation step determines whether specific qualities for the new migrant system can be achieved. (C) 2002 Published by Elsevier Science Inc.
