the characteristics of the data, and the characteristics of the data can be obtained by descriptive analysis of the data.Data Preparation (Date preparation): in the data preparation phase we need to choose, clean, rebuild and merge the data. Select the data to be analyzed and normalize the data that does not conform to the model input requirements.Modeling (Modeling): The modeling process is also a relatively important process in data mining. We need

requirements and the ultimate purpose from a business perspective. These goals are combined with the definition and results of data mining.2:data Understanding: Data is understood and collected to evaluate the available data.3:data preperation: Data Preparation, a series of organization and cleaning of available raw data to meet modeling requirements.4:modeling: The Application Data Mining tool builds the
