Architecture of e-learning systems based on LTSA

This paper propose an architecture for e-learning application. High demand of e-learning systems leads to the need of development of e-learning architecture. IEEE has defined the Learning Technology Systems Architecture (LTSA) as a standard for developing architecture of learning techonolgy systems (LTS). However, LTSA is considered too general. Thus, to build e-learning architecture, refinement of LTSA has to be conducted with a comprehensive approach. Several architectural frameworks have been proposed to model software architectures. Using one of these frameworks, a more detailed architecture is expected.
