Major tasks of data pre-processing

Data Cleaning

Data cleaning is a process to clean the data in such a way that data can be easily integrated.

Data Integration

Data integration is a process to integrate/combine all the data.

Data Reduction

Data reduction is a process to reduce the large data into smaller once in such a way that data can be easily transformed further.

Data Transformation

Data transformation is a process to transform the data into a reliable shape.

Data Discretization 

Data discretization converts a large number of data values into smaller once, so that data evaluation and data management becomes very easy.

After the completion of these tasks, the data is ready for mining.
