Abstract
E-Learning is one of most interesting topics in recent years. E-Learning system is not an ordinary system because it requires the integration of many technologies to be adaptive and effective more than other systems do. Service Oriented Architecture (SOA) claimed to satisfy complex and sophisticated systems functional and nonfunctional requirements, especially via adopting Web services as the main SOA enabler. This thesis presents a Services based Architecture that applies to UMIS and LMS components and consists mainly of two layers: Interface layer, and Services layer. Interface layer interacts with system users and with external organization services. Services layer contains core system services and has three sub layers: Orchestration, Application Services, and Agents layer. Pedagogically, Thesis shows that the proposed SOA based architecture has helped e-Learning to overcome lack of available well prepared courses by exploiting and automating courses shareability. Mobile assessment is facilitated by proposed architecture. The capability to integrate the different digital library contents and make it available to different LMS.
