Why Is Recovery Important? |
|
Answer» In every database SYSTEM, the possibility of a system or hardware failure always exists. Should a failure OCCUR and affect the database, the database must be recovered. The goals after a failure are to ensure that the effects of all committed transactions are reflected in the recovered database and to RETURN to NORMAL operation as quickly as possible while INSULATING users from problems caused by the failure.
