Self-adaptive Web Application Systems : Conceptual Architecture and Implementation Framework

Abstract

Self-adaptive systems, changing their functional behavior at runtime, provide the desired level of flexibility. Although various runtime frameworks have been studied, they tend to rely on a particular architecture. It is inadequate to study the intrinsic nature of self-adaptive systems. This paper presents an abstract, declarative framework for them and relates it to an adaptive PHP-based Web application architecture, which takes a model-based adaptation approach. Furthermore, the paper discusses the proposed approach with an example of simple EC-site application, and presents results of experiments conducted with the application.
