A Novel Method for Refactoring UML Metamodel

Refactoring Browser for UML

Refactoring is a corner stone in a number of agile processes like Extreme Programming (XP). Tools for an automatic support are beginning to appear, usually referred to as refactoring browsers. Most of these are extensions to editors or IDEs and operate on code. This paper discusses how the idea of refactoring can be extended to UML models and presents a refactoring browser integrated in a UMLmo...

A Rigorous Metamodel for UML Stati

Refactoring UML Models

Software developers spend most of their time modifying and maintaining existing products. This is because systems, and consequently their design, are in perpetual evolution before they die. Nevertheless, dealing with this evolution is a complex task. Before evolving a system, structural modifications are often required. The goal of this kind of modification is to make certain elements more exte...

Refactoring Use Case Models: The Metamodel

Formal Refactoring for UML Class Diagrams

Refactoring UML models for evolution is usually carried out in an ad hoc way. These transformations can become an issue, since it is hard to ensure that the semantics of models is preserved. We provide a set of semantics-preserving transformations for UML class diagrams annotaded with OCL. Using the proposed transformations, software designers can safely define larger transformations and detect...
