Data Cleansing Methods


Data cleansing or cleaning is the act of removing corrupt records from a set of data. It is also referred to as data scrubbing. Before a company starts any data related initiatives like ERP (Enterprise Resource Planning) or CRM (Customer Relationship Management) it is better to check on the data quality. Data cleansing involves use of various types of tools and software. Some of the cleaning methods/techniques include:

  • Data profiling
  • Data enrichment
  • Duplication elimination
  • Pattern matching
  • Checking for blank fields
  • Checking incorrect information
  • Correction of city and zip code errors
  • House holding
  • Checking consistency/completeness

Data cleaning services can be outsourced domestically or offshored to countries like India for better cost effectivity. Data cleaning can be done subjectively and objectively. It can also be done manually and in an automated way.

Cleaned data has to be updated with the legacy systems for a totally clean data environment.
