E-learning web services and their configurationpolicywithin terms of SOA

With the introduction of sophisticated communication technology, the idea of e-learning came into reality. Most of the e-learning systems are functioning in client server and distributed system settings. The activity of e-learning remained limited to specified requirement owing to the absence of appropriate dynamic software architecture of modern technologies. With the introduction of service-oriented architecture (SOA), an appropriate and superior solution framework has been suggested for e-learning. Different functions of e-learning system are implemented as stand-alone web services. The strength of the method adopted in this article is reusability and interoperability. To accomplish the new functionality in e-learning system, the construction of appropriate stand-alone web services is needed to make the system completely capable of interactive services making electronic teaching learning possible. Web service composition is a SOA-based methodology to create a composite web service using existing stand-alone or other composite services. In this article, we propose a full-fledged e-learning system with the assistance of web services and their construction as per SOA standard.
