ACID transaction

  • Type of database transaction with four properties:
    • Atomicity
      • Operations will either succeed or fail
    • Consistency
      • Transactions cannot bring the database into an invalid state
    • Isolation
      • Execution of multiple transactions concurrently will have the same effect as if they had been executed sequentially
    • Durability
      • Any committed transaction is written to non-volatile storage
      • Will not be undone by a crash, power loss, etc.
