Taxonomy for Evolution of Service-Based System

Abstract

With the rapid development of service computing related technology, the number of application of service based system (SBS) in enterprise is increasing rapidly. Research on evolution of SBS is becoming more and more important. In this paper, we propose a taxonomy framework for evolution of SBS, which is illustrated from five perspectives: (how). Furthermore, propagation of evolutionary changes of SBS is analyzed in the paper. (a) motivations of SBS evolutionary changes (why), (b) stakeholders of SBS evolutionary changes (who), (c) locations of SBS evolutionary changes happening (where), (d) times of SBS evolutionary changes happening (when), (e) support mechanisms in the process of SBS evolutionary changes

Analyzing the Evolution of Web Services Using Fine-Grained Changes

“…As future work, first we plan to classify the changes retrievable with WSDLDiff, integrating and possibly extending the works proposed by Feng et al [4] and Treiber et al [15]. Next, we plan to investigate metrics that can be used as indicators of changes in WSDL elements.…”

“…For instance Feng et al [4] and Treiber et al [15] have proposed approaches to classify the changes of web services taking into account their impact to different stakeholders. These classifications can be easily integrated in our tool to classify the different fine-grained changes extracted along the evolution of a web service.…”

“…The fine-grained changes extraction process of WSDLDiff is based on the UMLDiff algorithm [19] and has been implemented on top of the Eclipse Modeling Framework (EMF). 4 With WSDLDiff we performed a study aimed at analyzing the evolution of web services using the fine-grained changes extracted from subsequent versions of four real world WSDL interfaces. We address the following two research questions:…”
