Durability

Maintaining updates of committed transactions is critical. These updates must never be lost. The ACID property of durability addresses this need. Durability refers to the ability of the system to recover committed transaction updates if either the system or the storage media fails. Features to consider for durability:

  • recovery to the most recent successful commit after a database software failure
  • recovery to the most recent successful commit after an application software failure
  • recovery to the most recent successful commit after a CPU failure
  • recovery to the most recent successful backup after a disk failure
  • recovery to the most recent successful commit after a data disk failure

This book covers both issues. Managers at all levels of all organizations must be aware of both the changes that we are now seeing and ways to deal with issues created by those changes.
