What are Data Cleansing Tools?
Data cleansing or data scrubbing is a process for removing corrupt, inaccurate or inconsistent data from a database. Regular data-cleansing corrects records containing incorrect formatting, typographical mistakes, or other errors. Cleansing might also mean harmonizing records so that they are consistent with each other.
Data cleansing software systematically searches for discrepancies or anomalies by using algorithms or lookup tables. It then corrects the issues. An automated process of this kind is much more efficient than trying to fix errors by hand.
Regular data cleansing operations are critically important as erroneous data records can ultimately lead to erroneous conclusions and misguided investments decisions. Data cleansing tools often have featural overlap with data deduplication, data preparation, and data quality tools.
