摘要：

Historical steps such as processes of fabrication are each assigned a predetermined character code. Character codes are gathered and arranged in chronological order of the fabrication processes for their classification. Using such a classification method, a database is built to include records each storing a plurality of measured data and accommodating data fields for retaining historical data.
