Towards Service-Oriented Reference Model and Architecture to E-Learning Systems

K. PALANIVEL, S. KUPPUSWAMI

Abstract: E-learning systems are moving away from monolithic applications towards more open, flexible components, capable of interoperating with other learning components. In spite of the diversity of learning environments, there is a lack of uniformity regarding their basic functionalities. Thus, the establishment of core functionalities represents an issue to the development of learning environments. In a different but related perspective, reference architectures have emerged as an alternative for promoting reuse of design expertise and facilitating the development of Elearning systems. Reference architecture increases the scalability, flexibility and availability of e-learning systems. Service-oriented architectures (SOAs) provide a successful model for structuring complex distributed software systems, as they reduce the cost of ownership and ease the creation of new applications by composing existing services. Service-based architectures take legacy application functionality and expose it to the Internet in a reliable, highly available, scalable, flexible, manageable and secure manner, easy and reliable internet-based method to create and access learning. The objective of this paper is to provide Service-Oriented Reference Model and Architecture to e-Learning Systems (SORMALS). The SORMALSs designed to support maximum scalability and high service levels and an optimized management environment. It enables new levels of scalability while providing a very cost-effective modular solution. The key values of Interoperability, durability, compatibility, manageability, dynamic reusability and accessibility in the proposed architecture enhance the future e-Learning systems to communicate more efficiently and share data more easily. Keywords: Service-Oriented, E-Learning Systems, Personalization, Reference Model/Architecture, Scalability
