2. Algorithms for Recovery and Isolation Exploiting Semantics

   en.wikipedia.org/wiki/Algorithms_for_Recovery...

   In computer science, Algorithms for Recovery and Isolation Exploiting Semantics, or ARIES, is a recovery algorithm designed to work with a no-force, steal database approach; it is used by IBM Db2, Microsoft SQL Server and many other database systems. [1] IBM Fellow Chandrasekaran Mohan is the primary inventor of the ARIES family of algorithms. [2]

3. Data recovery - Wikipedia

   en.wikipedia.org/wiki/Data_recovery

   The most common data recovery scenarios involve an operating system failure, malfunction of a storage device, logical failure of storage devices, accidental damage or deletion, etc. (typically, on a single-drive, single-partition, single-OS system), in which case the ultimate goal is simply to copy all important files from the damaged media to another new drive.

4. Rollback (data management) - Wikipedia

   en.wikipedia.org/wiki/Rollback_(data_management)

   SQL refers to Structured Query Language, a kind of language used to access, update and manipulate database. In SQL, ROLLBACK is a command that causes all data changes since the last START TRANSACTION or BEGIN to be discarded by the relational database management systems (RDBMS), so that the state of the data is "rolled back" to the way it was before those changes were made.

5. Durability (database systems) - Wikipedia

   en.wikipedia.org/wiki/Durability_(database_systems)

   At this level, there is a strong bond between durability and system and data recovery, in the sense that the main goal is to preserve the data, not necessarily in online replicas, but also as offline copies. [4] These last techniques fall into the categories of backup, data loss prevention, and IT disaster recovery. [11]

6. Database administration - Wikipedia

   en.wikipedia.org/wiki/Database_administration

   One key skill required and often overlooked when selecting a DBA is database recovery (a part of disaster recovery). It is not a case of “if” but a case of “when” a database suffers a failure, ranging from a simple failure to a full catastrophic failure. The failure may be data corruption, media failure, or user induced errors.

7. Write-ahead logging - Wikipedia

   en.wikipedia.org/wiki/Write-ahead_logging

   A write ahead log is an append-only auxiliary disk-resident structure used for crash and transaction recovery. The changes are first recorded in the log, which must be written to stable storage, before the changes are written to the database. [2] The main functionality of a write-ahead log can be summarized as: [3]
