A platform-independent aspect-oriented model and patterns to support model transformations

Model Driven Architecture (MDA) separates application logic from specific implementation technology to improve the reusability, portability and maintainability of the software system. However, current software system also needs to deal with other important concerns that are called crosscutting concerns that explicitly addressed by Aspect-oriented Programming (AOP). In this dissertation, we propose a model-driven approach to assess the benefits of AOP for MDA in order to provide increased modularity and to support related quality attributes. Even though research has been conducted toward modeling crosscutting concerns, these approaches found to be either language dependent or provide no support for aspectual behavior. This work has two contributions. First, we complement current works by proposing a language-independent extension to the UML metamodel to explicitly capture crosscutting concerns. The second contribution is to provide well-defined and automated model transformations to work with different models at various levels of abstraction and preserve their consistency
