What is Data Cleansing and Why is it Used?

Data is present in every business and it comes in various forms. Nowadays, many businesses may not be able to operate efficiently if they are not provided with certain information. For example, a doctor or dentist need to have your previous medical or dental record on file for the next time you schedule an appointment. Similarly, an ecommerce company needs to collect data, such as your search history and preferences, if they are to provide you with relevant, targeted advertisements.

However, the introduction of GDPR (General Data Protection Regulation) on May 25th 2018 aims to clamp down on those companies who misuse the sensitive and personal information of their users. Its aim is to give more control to users over their personal data and penalises any business who mistreats (such as sells data to a third-party) this data.

Having said this; data cleansing has become extremely important for businesses all over Ireland and the EU. It is the action of:

  • Removing duplicate data
  • Amending incorrect data
  • Amending incomplete data
  • Removing irrelevant & unnecessary data.

Accurate and quality consumer data are essential in the decision-making process and it can contribute to the success of the business in the long-term.
