ABSTRACT In recent years data mining gets more and more attention and becomes one of the hottest spot in IT research field. Researchers from various fields show great enthusiasm for the subjects in data mining and are willing to devote themselves to the new field because data mining syncretizes artificial intelligence, statistics, database, and machine study. At the beginning of this new century, it is a large-scale amalgamation of subjects.

短短的几年时间，数据挖掘风靡全球，成为IT业近年来非常热门和前沿的研究方向之一，由于数据挖掘融合了人工智能、统计学、数据库、机器学习等各个领域的理论与技术，使得不同学科领域的学者对DM的研究表现出了前所未有的热情和参与精神，在世纪交替的特殊时期，这是又一轮规模空前的学科大融合。

The basic concept and general knowledge of data mining were given firstly, and the characteristics and research methods of data mining procedure were explained based on the test-driving database of WS9 aero-engines. Rough set and decision tree, these two classification mining methods were used to extract decision rules, regression analysis was utilized to find the relationship between variables, and the tendency also was predicted.
