Definition - What does Data Preprocessing mean? Data preprocessing is a data mining technique that involves transforming raw data into an understandable format. Real-world data is often incomplete, inconsistent, and/or lacking in certain behaviors or trends, and is likely to contain many errors. Data preprocessing is a proven method of resolving such issues. Data preprocessing prepares raw data for further processing.
Data processing is the re-structuring or re-ordering of data by people or machine to increase their usefulness and add values for a particular purpose. Data processing consists of the following basic steps - input, processing, and output. These three steps constitute the data processing cycle. 1  Input â In this step, the input data is prepared in some convenient form for processing. 2  Processing â In this step, the input data is changed to produce data in a more useful form. 3  Output â At this stage, the result of the proceeding processing step is collected.
