Design and implementation of an e-learning platform using N-tier architecture

Abstract

Any educational institution aimed at developing towards elearning and creating a more interactive environment and use in all fields of governmental institutions. The Ministry of Higher Education and Scientific Research (MOHESR) of Iraq and some of the countries in the Middle East suffer from weak use of information technology in general and weak use of elearning in particular. Therefore, Iraqi MOHESR is in dire need of an electronic educational system that solves most of the problems experienced by most educational institutions. In this paper, we will develop a strategic plan to build an e-learning platform that provides an interactive environment between teachers and students in Iraqi universities and offers many advantages to overcome some problems in the use of traditional old education. This work is related to the use of multi-layered architecture to build the e-learning platform (Standard design of e-learning platform for Iraqi MOHESR). The advantage of these layers is that each layer is created in the Asp. Net program using N-Tier architecture that has functions that are independent of the rest of the layers which are(user interface(UI), business Access Layer(BAL), Data Access Layer(DAL), Database(DB). A particular object will not affect the rest of the layers or the performance of these layers.
