Abstract

As software development becomes large-scale, the major focus of the developers has shifted from algorithms and data structures to architectures of the software systems. Architecture provides a bridge between requirements and implementation. Until recently, mechanism for self adaptation is largely in the form of programming language features embedded in code, thus prohibiting reusability and modifiability. This paper advocates the use of an external mechanism which monitors the running system and updates the architectural properties based on the changes in the system. Haphazard changes made in the architecture might make the system unstable. In order to address this issue, this paper proposes an approach for dynamic self adaptation by integrating the adaptive framework with architectural patterns. Since the architectural patterns have some predefined and proven structure, they make the system amenable for easy adoption. The changes in the architecture are mapped back to the running system. The external mechanism thus monitors and makes changes to the running system dynamically. The proposed approach has been tested by applying it to a sample e-Shopping application case study.
