This is nothing but polising of data. For example of one of the sub system store the Gender as M and F. The other may store it as MALE and FEMALE. So we need to polish this data, clean it before it is add to Datawarehouse. Other typical example can be Addresses. The all sub systesms maintinns the customer address can be different. We might need a address cleansing to tool to have the customers addresses in clean and neat form.
