Abstract

Legacy systems are those that have built numerous business rules of an organization and accommodating knowledge of years of maintenance. Many of them are still vital for organizations but have serious maintenance problems. One way to improve the quality of a legacy system is to submit it to a restructuring process, whose goal may range from improving its modularity, modify its architecture to meet architectural rules, adopt design patterns or even use a combination of these techniques . There is currently a lack of approaches that provide adequate support throughout the restructuring process, the majority focuses on isolated parts of this process. In addition, restructuring activities are often conducted without a clear specification of the existing problem and desired solution. In this project, the goal is to develop an approach that presents alternative of restructuring scenarios based on desired quality requirements. The flow of this approach starts with the specification of "quality requirements" that are expected to be served after the system is restructured. After that, a tool should provide a set of scenarios for restructuring and show quantitatively the impact of each of the specified quality requirements. Thus, the software engineer can analyze the pros and cons of each scenario and choose for one that is best suited to current interests. After selecting one or more sets of the system is automatically restructured.
