| Abstract: | Database System takes a variety of protective measures to prevent database security and integrity from being destroyed,and ensure the correct implementation of complicated Transactions.But the computer system hardware failures,software errors,operator errors and vandalism are still inevitable.These failures will cause non-normal interruption of the running operations and affect the accuracy of the data in the database.Some failures even damage the database and cause the database loses all or part of the data.Therefore the database management system must have the function to restore the database from the wrong state right to a known correct state(also known as the integrity state or consistent state),which is the restoration of the database.Common recovery technology include: data dump and sign a log file. |
