| Resumo: | Aspect-Oriented Software Development (AOSD) is a technique that complements the Object-
Oriented Software Development (OOSD) modularizing several concepts that OOSD
approaches do not modularize appropriately. However, the current state-of-the art on AOSD
suffers with software evolution, mainly because aspect definition can stop to work correctly
when base elements evolve. A promising approach to deal with that problem is the definition
of model-based pointcuts, where pointcuts are defined based on a conceptual model. That
strategy makes pointcut less prone to software evolution than model-base elements. Based on
that strategy, this work defines a conceptual model at high abstraction level where we can
specify software patterns and architectures that through Model Driven Development
techniques they can be instantiated and composed in architecture description language that
allows aspect modeling at architecture level. Our MDD approach allows propagate concepts
in architecture level to another abstraction levels (design level, for example) through MDA
transformation rules.
Also, this work shows a plug-in implemented to Eclipse platform called
AOADLwithCM. That plug-in was created to support our development process. The
AOADLwithCM plug-in was used to describe a case study based on MobileMedia System.
MobileMedia case study shows step-by-step how the Conceptual Model approach could
minimize Pointcut Fragile Problems, due to software evolution. MobileMedia case study was
used as input to analyses evolutions on software according to software metrics proposed by
KHATCHADOURIAN, GREENWOOD and RASHID. Also, we analyze how evolution in
base model could affect maintenance on aspectual model with and without Conceptual Model
