RE: what is data cleaning? how is it done?
It is nothing but purifying data , the extract process always exposes the data qulaity issues that have been bured within the operational source system. Since the data qulaity significantly impacts data warehouse credibility , you need to address these qulaity problems during the data staging which is nothing data cleaning.
