Database model ACID rules..

Wednesday, June 30th, 2010 @ 5:08 pm


  • Atomicity states that database modifications must follow an ‘all or nothing’ rule.
  • Consistency states that only valid data will be written to the database.
  • Isolation requires that multiple transactions occurring at the same time not impact each other’s execution.
  • Durability ensures that any transaction committed to the database will not be lost.
