E-Learning Web Services and Their Composition Strategy in SOA

Abstract

With the advent of advanced communication technologies, the concept of e-learning came into practice. Most of the e-learning systems are operating in client server and distributed system environment. The activity of e-learning remained confined to predefined need due to the lack of suitable dynamic software architecture of newer technology. With the advent of service-oriented architecture (SOA), a suitable and better solution framework has been proposed for e-learning. Different functions of e-learning system are implemented as stand-alone web services. The strength of the approach followed in this paper is reusability and interoperability. To achieve the new functionality in e-learning system, the composition of relevant stand-alone web services are required to make the system fully capable of interactive services making electronic teaching learning feasible. Web service composition is a SOA-based model to make a composite web service by existing stand-alone or other composite services. In this paper, we present a full-fledged e-learning system with the help of web services and their composition as per SOA standard.
