A survey on service-oriented architecture for E-learning system

E-learning refers to learning that is delivered or enabled via electronic technology. E-learning is classified as synchronous or asynchronous. Service based technology in e-learning provides a common infrastructure to integrate heterogeneous software components, thus enhancing interoperability between different components. Service-oriented architecture for e-learning provides adaptable, interactive, extensible, distributed, collaborative and intelligent e-learning system to effectively realize the learning anytime and anywhere to instructors and learners. This paper presents a detailed analysis of well known architectures for service based e-learning system. The architectures that surveyed here gives users the ability to collect, analyze, distribute and use e-learning knowledge from multiple knowledge sources.
