Archiving
Archiving data enables you to manage database growth and maintain system performance by moving data from live transactional tables to archive tables, keeping the archived data accessible when needed. You can also purge archived data through separate action. Purging data from an archive table permanently removes the data.
When archiving is enabled and an application action purges data from live tables, the Landmark framework automatically moves the data to archive tables as part of the purge process if the BusinessClass is defined as archivable.
