A Case Study of the Development of e-Learning Systems Following a Component-based Layered Architecture

The development of flexible, reusable and interoperable LMSs has increasingly attracted the attention of the e-learning community. Considering these issues, the TIDIA-Ae project has been proposing a component-based solution for LMSs development. This article presents a development case study according to the TIDIA-Ae's component-based architecture, whose activity was the development of the Portfolio and Weblog tools. The main artifacts obtained in the development process, the solutions adopted for the open issues and the main learned lessons are presented.
