A Model for Developing Component-Based and Aspect-Oriented Systems

چکیده
Abstract. Aspect-Oriented Programming (AOP) and Component-Based Software Engineering (CBSE) offer solutions to improve the separation of concerns and to enhance a program structure. If the integration of AOP into CBSE has already been proposed, none of these solutions focus on the application of CBSE principles to AOP. In this paper we propose a twofold integration of AOP and CBSE. We introduce a general model for components and aspects, named Fractal Aspect Component (FAC). FAC decomposes a software system into regular components and aspect components (ACs), where an AC is a regular component that embodies a crosscutting concern. We reify the aspect domain of an AC and the relationship between an AC and a component, called an aspect binding, as first-class runtime entities. This clarifies the architecture of a system where components and aspects coexist. The system can evolve from the design to the execution by adding or removing components, aspects or bindings.

Aspect-Oriented Requirements Engineering for Component-Based Software Systems
Developing requirements for software components, and ensuring these requirements are met by component designs, is very challenging, as very often application domain and stakeholders are not fully known during component development. We introduce a new methodology, aspect-oriented component engineering, that addresses some difficult issues of component requirements engineering by analysing and ch...
متن کاملApplication of Aspect-based Modeling and Weaving for Complexity Reduction in Development of Automotive Distributed Real-time Embedded System
To meet the stringent resource and costs constraints in developing modern automotive embedded electronic systems requires careful consideration of various aspects, such as the target hardware structure, component collaboration model, and timing models. An emerging trend in automotive systems is to apply Model-Driven Development (MDD) to understand and formalize these aspects. The growing size a...
متن کاملDeveloping .NET Web Service-based Applications with Aspect-Oriented Component Engineering
Current approaches to engineering web service-based software systems are limited by lack of comprehensive web service component characterisations. In this paper, we describe our recent work applying Aspect-Oriented Component Engineering (AOCE) to develop more adaptable, higher quality and more reusable software components for web services. We give examples on how AOCE can be used to design and ...
متن کاملAspect IPM: Towards an Incremental Process Model Based on AOP for Component-Based Systems
In spite of recent and constant researches in the Component-Based Development area, there is still a lack for patterns, processes and methodologies that effectively support either the development “for reuse” and “with reuse”. This paper presents Aspect IPM, a process model that integrates the concepts of component-based software engineering, frameworks, patterns, non-functional requirements and...
