System Design through the Exploration of Contemporary Web Services

Abstract

In this article, we develop a Contemporary Web Service (CWS) repository of system designs, which are encoded as metadata of contemporary web services. We examine if this CWS repository serves as an effective design tool for initial CWS design and as an effective support tool for business users and analysts working together on system design. The CWS repository reduces the cognitive load of both the analyst and the business user as they jointly explore the CWS repository of system designs. It supports an evolutionary approach to system design through rapid selection of appropriate CWS metadata. To accomplish that, we introduce several new design characteristics for the CWS repository. The evaluation results demonstrate that the CWS repository is an effective tool for supporting designers during initial service design, as well as for supporting business users and analysts during system design.

Service-oriented Application Composition with Evolutionary Heuristics and Multiple Criteria

“…Selecting from the set of viable services requires the use of non-functional characteristics. Many of these non-functional aspects of services have been operationalized as quality of service (QoS) measures, including performance, reliability, security, availability, supportability, maintainability, data integrity, and cost, among others (Benlian et al 2011;Cardoso et al 2004;OASIS 2004;Ran 2003;Hashmi et al 2016;Delano et al 2018). Performance, security, reliability, and cost are the most important and widely used objectives in service selection.…”
