Use of Persistence layer in SAP HANA

SAP Persistence layer is required in the following scenarios −

• In any database, main memory is volatile therefore data is lost during a restart or when a power outage occurs.
• Data needs to be stored in persisted medium.
• Backup & Restore is available.
• It ensures that the database is restored to the most recent committed state after a restart and that transaction are either completely executed or completely undone.
