What does Data Purging mean?
Data purging is a term that is commonly used to describe methods that permanently erase and remove data from a storage space.

Techopedia explains Data Purging
Methods for data purging in database administration include automatic purging features. For example, some Microsoft products support an automatic purge technique that uses a circular buffer methodology, in which older data is automatically purged to make way for newer data. In other cases, administrators must manually purge data from the database.
Setting up data purging solutions can raise questions for developers, database administrators and others with these kinds of responsibilities. Issues involved in setting up data purging methods include questions about server operation and client access during the data purging process. Other questions involve how to access the right data purging tools or how to plan practices for a specific technology such as a database.
