A Comparison of Aspect-oriented Approaches to
Model Driven Engineering

• Outline
• Overview of model driven engineering
• Challenges in model driven engineering
• Overview of AOMDE approaches
• Generate-Then-Weave Approaches
• Lessons Learned and Future Work

4
MDE Challenges

• Model specification
• Model transformation
• Model analysis
• Model evolution and reuse
• Model debugging

5
MDE is difficult in the presence of crosscutting
functionality
Tangling!!
6
Crosscutting Functionality
An Aspect-Oriented Approach is beneficial

• In AOSD crosscutting functionality is isolated in
  modular units called aspects.

Computation may then be represented as
permutation P(2,2)P(3,3) which means there are
2!3! or 12 valid combinations.

Lessons Learned

• AOMDE requires an understanding of how AOSD
  affect MDE lifecycle.
• MDE is not a unary model-to-code process
• A variety of approaches are available.
• Further research needed to explore AOMDE in both
  initial development and evolution
