Data scrubbing is the act of revising or removing information from a database that is either incorrect, missing, or redundant. Errors in data result from human error during entry, database merging, or aging systems. This error correction method is also known as data cleansing or data cleaning. The main goal of data scrubbing is to remove errors and inconsistencies in order to improve the quality of the information within the database. Data scrubbing can be performed manually or by using specific scrubbing tools.
