This course covers the essential concepts, principles, techniques, and mechanisms for the design, analysis, use, and implementation of computerized database systems. Key information management concepts and techniques are examined: information modeling and representation; information interfaces - access, query, and manipulation, implementation structures, and issues of distribution. The database and information management system technology examined in this course represents the state-of-the-art, including traditional approaches as well as recent research developments. By providing an imbalanced view of "theory" and "practice," the course should allow the student to understand, use, and build practical database and information management systems. The course is intended to provide a basic understanding of the issues and problems involved in database systems, a knowledge of currently practical techniques for satisfying the needs of such a system, and an indication of the current research approaches that are likely to provide a basis for tomorrow's solutions.
