Design methodology of an educational computer-aided telematics service

This paper discusses the development of an adaptable computer-aided learning educational environment for teaching telematics courses and suggests a proper design and implementation methodology. The proposed service will use many currently available state-of-the-art tools and techniques in telematics and computer-aided education. A structured methodology for designing and implementing the CAL service is presented, based on the Open Distributed Processing (ODP) principles. According to this standard the system must be viewed from five different perspectives: enterprise, information, computational, engineering and technological viewpoint. Each viewpoint focuses on different issues, and all together give a global and complete description of the CAL service, clearly defining all subsystems and subservices.
