Arhitectura of a computer based instructional system
The paper describes the architecture of a tutorial system that can be used at various engineering graduate and postgraduate courses. The tutorial is using Internetstyle WWW services to provide access to the teaching information and the evaluation exercises maintained with a RDMS. The tutorial will consist of server-side applications that process and present teaching material and assessing exercises to the student using the well-known Web interface. All information in the system will be stored in a relational database. By closely sticking to the ANSI SQL specifications, the system can take advantage of a free database managing system running on Linux, the mini-SQL. The tutorial can be used to on-line deliver any courses, creating new, continuing education opportunities. Taking advantage of the modern deployment techniques, the instructional/assessing tutorial offer high degrees of accessibility.
