Methods used for data cleaning:

Reviewing Data
The cardinal step for data cleaning, should always be to review the customer databases completely right at the start. Check any deviations or inaccurate data by analysing/auditing the database with the help statistics and database techniques. The data generated via these methods should then help you to figure out the location and attributes of the deviations helping you to reach the root of the problem.

Employing different methods
The reviewing of the database should not be restricted to just using the statistical or database techniques. The reviewing process must also include methods like purchasing data from outside and then analyse it in comparison to the internal data. But, if that does not suffice and the enterprise is facing a challenge with limited staff and time, use of an external telemarketing company is a better idea. However, here it’s important for the company to be careful about their brand image and the work standards followed by the external organization (third-party).

Data integration
Data cleaning is not just about finding and deleting inaccurate data from the customer database, but it should be rather used to the company’s advantage to integrate customer information and added details such as, phone numbers, email address, or any other contacts time and again.

Reporting of information
Businesses must ensure that there’s a robust management system within the organization that can timely and effectively identify and report any incorrect data and it’s update in the database. This can be achieved by a managed and feedback system intended for emails and any email that bounced back because it was not the right address. This anomaly should be reported and the incorrect email address should be removed from the customer database.

Repeat the same process
It’s a constantly progressive world where everything is changing so fast, that businesses must be able to keep up with the fast pace and so, customer data like, company email address, phone numbers, mailing addresses, etc. change very often. Therefore, simply running a one-time data cleansing process would not be the solution and thus, repeating the same data cleansing process on a regular basis is extremely important. Filtering of such inaccurate data and update of the customer database on a regular basis is the only way out to make sure that the company has a clean database.

Yes, data cleansing is a major process that is critical and time consuming. Given that it requires a lot of time, effort and resources, it is a wise decision to use the reputed data cleansing tools available these days.
