What is the Difference between Archiving and Purging in Oracle database? I would like to know the main difference between Archiving and Purging in any database we use.
Purge Process

Purging is the process of freeing up space in the database or of deleting obsolete data that is not required by the system. The purge process can be based on the age of the data or the type of data.

Archive Process

Archiving is the process of backing up the obsolete data that will be deleted during the purge process. During the archive process, data will be moved from the main transactional tables to the backup tables.
