The second is to consider the high efficiency of the DB2 data backup and recovery solution. If it takes several hours to back up or recover a DB2 database, the backup and recovery solution will be safe in a tim

The principle of transaction and database recovery The logical unit of data storage is the data block, and the logical unit of data manipulation is the transaction. A transaction is a user-defined set of sequence of operations, consisting of one or more related SQL statements, which is the basic logical unit of a database application. Transaction management technology mainly includes database recovery tec

the inconsistent translations of various technical documents, the specific concepts are different. In Oracle databases, three types of Database Backup are called full backup, differential incremental backup, and cumulative incremental backup. Incremental incremental is the Incremental backup we mentioned above, while incremental is the differential backup we mentioned above. In order to unify the text, the author still uses Differential backup and Incremental backup in the following explanation
