Abstract: To the common of decision tree and data warehouse in the data mining field, this paper creatively combines both of them. In order to provide fully decision support, it includes combination of representation and operation based on Online Analytical Processing(OLAP). After adopting the combination, the problems such as high storage occupation, low query speed and high error probability of classified decision information which resulted from decision tree’s increasing are conquered. After applying this combination to some travel agency’s client information database, this project turns out a affirmative feasibility and superiority.

Key words: data mining, decision tree, data warehouse, decision support, Online Analytical Processing(OLAP)
