A learning management system (LMS) is software for delivering, tracking and managing training. LMSs range from simple systems for managing training records to software for distributing courses over the Internet and offering features for online collaboration. In many instances, corporate training departments purchase LMSs to automate record-keeping as well as the registration of employees for classroom and online courses. Student self-service (e.g. self-registration on instructor-led training), training workflow (e.g. user notification, manager approval, waitlist management), the provision of on-line learning (e.g. Computer-Based Training, read & understand), on-line assessment, management of continuous professional education (CPE), collaborative learning (e.g. application sharing, discussion threads), and training resource management (e.g. instructors, facilities, equipment), are some of the additional dimensions to leading Learning Management Systems. http://en.wikipedia.org/wiki/Learning_management_system
