The advantages of using an electronic product catalog instead of a traditional paper one have been recognized by many people.
Some vendors now offer electronic product catalog on CD-ROM or even on the internet.
However, most of these catalogs are somewhat affected by paper catalogs and have not used computer technology to the full extent. We try to build an electronic product catalog based on advanced database, networking, expert system, multimedia technologies. It provides product information as well as guidance in selection. In addition, an effective query engine for selection in different levels is implemented. The information is stored and presented in most effective formats, e.g., data, text, image, CAD file, animation, etc.
