Collecting, managing and processing course material requires of much costs and efforts while they include a variety of data types particularly in the health field. Some engineering work on the material may help reduce the workload and costs to some extent. With such benefits having in mind, this paper tries to develop multimedial database for the course material of Oral Pathology in dental schools. It provides structured analysis of data for the course material, in which a unit of disease is a central class with relation to many other classes. It also achieved data independence from server applications by using the method concept of object-oriented database(OODB), which will increase reusability of the course data. Using another important concept of OODB, the system devised many functional utilities on an Internet web server including lecture notes, case studies, disease search, and question and answer, and shows how they are operated. But the effectiveness for the part of student users may remain to be evaluated.
