This is where validation is important, which is a process that ensures data is logical and reasonable. Verification is conducted to ensure data entered is true to the original source. Some of the methods used include:-


  • Proof Reading – data is checked by manually comparing it with the original document.
  • Double Entry Checks – data is reentered and the two copies are compared for discrepancies.
  • Other methods also include phone and email verification.


While manual methods may be time consuming and expensive, new software technologies have been developed to automate the data verification process, proving to be cost effective as well as faster.

‘High Volume’ Data Sources Are Not As Clean As You Think!


  • Online Data Sources – while using data collected from web forms, web registrations, lists, spreadsheets and other online data collection tools; do not directly dump it into the database. More often than not people do not enter information correctly online. Therefore this data needs to be scrubbed cleaned of errors before contaminating an existing database.



  • Crowdsourcing – is a community driven concept data hk  wherein data is contributed by users. Various groups and people provide information such as email addresses, phone numbers and social media profiles. This source provides unlimited amount of data and information, making it possible build databases that could effectively utilized.

While new processes and technologies have been developed to maintain ‘clean and green’ databases, a simple method to begin with could be:


  • Formalize strategies – Companies need to define their objectives to ensure data management is organized and databases built in direction with the company’s strategic goals.
  • Fine tune processes – To ensure strategies are implemented efficiently, processes need to be streamlined. Creating a map is a great of identifying different stages of the data cleansing process.
  • Focus on data integrity – Once data cleansing programs are in place, it is important to integrate clean data with existing databases. To avoid clutter and muddling of old data, with new data or bad data, it is important to ensure integration processes are tight.
  • Formulate an ongoing data cleansing program – Cleansing data once is not going to clean new data that pours in on a daily basis. An ongoing program needs to be formulated to maintain quality of new information being introduced.
