A Framework for Evaluating Model-driven Architecture

Abstract

In the last few years, Model Driven Development (MDD), Component-based Software Development (CBSD), and contextoriented software have become interesting alternatives for the design and construction of self-adaptive software systems. In general, the ultimate goal of these technologies is to be able to reduce development costs and effort, while improving the modularity, flexibility, adaptability, and reliability of software systems. An analysis of these technologies shows them all to include the principle of the separation of concerns, and their further integration is a key factor to obtaining high-quality and self-adaptable software systems. Each technology identifies different concerns and deals with them separately in order to specify the design of the selfadaptive applications, and, at the same time, support software with adaptability and context-awareness. This research studies the development methodologies that employ the principles of model-driven development in building self-adaptive software systems. To this aim, this article proposes an evaluation framework for analysing and evaluating the features of model-driven approaches and their ability to support software with self-adaptability and dependability in highly dynamic contextual environment. Such evaluation framework can facilitate the software developers on selecting a development methodology that suits their software requirements and reduces the development effort of building self-adaptive software systems. This study highlights the major drawbacks of the propped model-driven approaches in the related works, and emphasise on considering the volatile aspects of self-adaptive software in the analysis, design and implementation phases of the development methodologies. In addition, we argue that the development methodologies should leave the selection of modelling languages and modelling tools to the software developers.

Design and Implementation of Autonomic Simulator

“…Rainbow framework is an architecture-based approach in which adaptation is accomplished through the implementation of an adaptation strategy chosen at runtime [10]. Model-Driven approach is a framework that provides model-based support for developing pervasive systems in order to add a resource or eliminate resources from a system [11,12]. Meta-Self is a service-oriented framework that provides controllable and dependable engineering requirements for supporting the development of SASs [13].…”
