Revolution2: A Tool for Enterprise Application Evolution Based on Requirement-Driven Approach

The main problem of enterprise application evolution is how to capture requirements and then propagate requirement changes to application. Effectively evolving enterprise application with the frequently changing requirements is still a challenge to software engineering. Requirement is the root causes of evolution of enterprise applications in many cases. Refactoring has given guidance to gradual evolution of object-oriented software. This paper presents a tool - Revolution2 - for designer to evolve enterprise applications. The tool is implemented based on a requirement-driven approach which uses refined use cases to capture the requirements and changes, and propagates the changes through refactoring mappings between requirements and models. The tool helps to effectively maintain model and other parts of the application, which smoothes the evolution process of enterprise applications.
