A model weaver for dynamic evolution base on MDA aspect-oriented software architecture

Model weaving is a new research topic in MDA (Model Driven Architecture), and it is also the one of the research hotspots in aspect-oriented software architecture. At present, there are two key issues, evolution and complexity, need to be resolved in software engineering, and some researchers have proposed a model weaving framework which based on MDA. However, they didn´t propose a complete model weaver. In this paper, we focus on designing a complete model weaver to support Aspect-Oriented dynamic software evolution in architecture level. Hence, combining MDA with AOP, we propose a MDMW weaver. Thus, a new method to resolve maintenance of software complexity and management of the software evolution in the abstraction layer of software architecture was provided. By separating concerns, modeling the crosscutting concern and the function need to be extended as aspectual model, the abstract level can be improved, then we weaving it into base model by MDMW weaver. It is well regulated, executable, and can achieve the software evolution and maintenance easily.
