A system to accumulate technical information on casting defects was developed using a relational database method. This system enables effective use of various technical information from casting workshops which are the key to improving casting technology. We also developed a system to share information on casting technology over the Internet. Consequently, with no restriction of time and space, this system realizes information sharing on casting defects and provides the venue for virtual discussion among engineers.
