Decision tree algorithm is an important algorithm in data mining.This paper introduces the data pre-processing methods and decision tree construction method and steps.Data preparation is to enhance the quality of data mining objects.It includes data cleaning,data integration and data reduction.By selecting the appropriate attributes as roots,sub-roots repeatedly on the basis of training sample collection,eventually,it can establish the optimized decision tree after preprocess data.
