Supporting crosscutting concern modelling in software architecture design

Abstract

Crosscutting concerns such as logging, security, and transaction, are well supported in the programming level by aspect-oriented programming technologies. However, addressing these issues in the high-level architecture design still remains open. This paper presents a novel approach to supporting crosscutting concern modelling in the software architecture design of component-based systems. We introduce a new element named "Aspect" into our architecture description language, ABC/ADL, to clearly model the behavior of crosscutting concerns. Aspect is the first class entity as Component and Connector in ABC/ADL. ABC/ADL Connectors provide the weaving points where the component and aspect crosscut. This approach effectively enables "separation of concerns" in high-level architecture design, and facilitates black-box reuse of COTS components.

Behavior Consistency Verification for Evolution of Aspectual Component-Based Software

“…The software dynamic evolution helps to improve system's adaptability and flexibility, to extend the lifetime of system and to improve the expansibility of system [1]. Aspect-oriented method is unifying the decentralized public code crosscutting in other function modules to form aspect to achieve the absolute separation of system concerns .At the meantime, using weaving mechanism can weave aspects into the component system according to the need, and form aspectual component-based system [2]. The dynamic evolution of aspectual component-based system is a complicated process.…”
