Architecture of Modern E-Learning Management System

Abstract-In contemporary educational institutions, a robust Learning Management System (LMS) plays an important role within the E-Learning infrastructure. An LMS serves as an organized repository for course materials while also incorporating vital communication features like discussion forums, annotations, and chats. The LMS encompasses tools designed to monitor students’ advancement through course materials and assess the knowledge they acquire during their learning journey. Since the LMS is a complex software application, which operates for extended periods of time, it needs a careful consideration of its design in terms of functionality, dependability, and lifecycle management. In this paper, we present the architecture of a modern LMS called WBT-Master. This architectural framework is referred to as CDAT, representing Controller, Data, Activity, and Template. The "Activity" assumes a central role within the application. It processes the incoming data according to its designated purpose, and visualizes the data on the user’s screen. The “Template” element comprises HTML fragments containing placeholders The placeholders are bound to the activity variables. “Controllers” act as event handlers and load the different activities depending on user actions. “Data Provider” offer a unified data representation on diverse data sources. We also explore the system’s data organization principles and its seamless integration with popular cloud services.
