  1. MDA and Separation of Aspects: An approach based on multiples views and Subject Oriented Design Quercus Software Engineering Group Computer Science Department University of Extremadura, Spain Pablo Amaya, Carlos González and Juan M. Murillo

  2. Outline • Introduction • Model-Driven Architecture • The problem!! • The proposal • Case study • Subject Oriented PIM and PSM • Traceability, evolution and change impact • Conclusions and future works MDA and Separation of Aspects: an approach based on Viewpoints

  3. transformation transformation Introduction CIM • Model-Driven Architecture • OMG’s initiative • To enable Model-Driven Development • Three abstraction levels • To improve • development of large complex system PIM PSM MDA and Separation of Aspects: an approach based on Viewpoints

  4. Introduction • Large complex systems • e-government • Software development with MDA • Problems • Each model becomes large and monolithic • Models are not manageable, reusable, adaptable, etc. • Transformations between models are too complex. • Objectives • To improve : • modeling • traceability • evolution • … • Solution: Separation of Aspects in all MDA levels.

  12. Conclusions and Future Works • Improvements in MDA • Concurrent Development • Evolution • Change Impact • Additive vs Invasive • Change propagation • Traceability • Models more reusable, manageable and adapatable • To allow us to develop aspect repositories • Future work directions • In general: To mature the proposal • A Foundation for view repositories • To model CIM with other diagrams • Workflow, domain models,activity diagrams. etc. • To enhance relationships between views • Intregation of views at model or code level • Order of composition • Consistency Check • Transformations between aspect-models MDA and Separation of Aspects: an approach based on Viewpoints
