Data transformation is the process of transforming raw data into a format that is easier to use and interpret for the purpose of data mining as well as recovering strategic information. In order to change the data into the right form, data transformation techniques include data cleansing and data reduction.
As the name suggests, data transformation tools are the assets a business can use to make that happen. Data transformation tools assist in changing data formats and applying business logic to raw data. This is particularly important when combining structured and unstructured data from many sources for analysis.
