An online portal provides a platform for students to effectively study various courses with self-assurance; supported by various institutions to ensure the accuracy of information available. The aim of this review is to provide an informed overview of e-learning platforms and review different features of Learning Management Systems (LMSs), while exploring its implications, general issues and challenges. It also discusses the e-learning pedagogical perspective in Azerbaijan.
