Three substages of data preparation.

Data preparation	Explain
Data selection		Selecting a file usually involves deleting data affected by an existing file or database to create a target file
Data preprocessing		Data preprocessing process extracts data to meet the requirements of data mining
Data transformation		The main purpose of exchanging data is to reduce the width of the data, that is, to find the main features of the first feature in order to reduce the number of features or differences in data mining
