Data Cleansing

Data cleansing is also referred to as data scrubbing. This is the basic and initial step of the Master Data Management (MDM) process flow. The rapid growth of e-commerce has increased the integration of multiple databases for which data cleansing is the must to ensure that the data in each database is standard, consistent and accurate to eliminate the errors.

It is the act of amending the data from the database by detecting and correcting corrupt or inaccurate data which is improperly formatted, incomplete, incorrect or duplicated. Usually data is held with duplicates and irrelevant data which should be eliminated by data cleansing.
