E-learning systems have become an issue in recent years. This book is about developing a computer program in order to evaluate the LMSs. The developed system is web-based and can easily be used over the internet any where over the world at any time. This will provide with a web-based DSS that may help the users to choose the convenient system depending on their needs and their type of usage. In order to evaluate the LMSs, we must consider the most important features of any LMS and put them as the criteria that may enable us to evaluate the systems. In this study, fifty two comprehensive features of any e-learning system are presented. The user can select his group of features from the list of 52 commonly used features. The system can then find the best LMS to match the selection criteria. This book is oriented to anyone interested in the e-learning field and its evaluation. The individuals who are usually concerned with this project are teachers, students, and any educational organizations such as: universities, schools, institutes, and anyone who seeks to have a LMS.
