ACID properties, essential properties of the transaction processing subsystem of a database management system, include

  • Atomicity: a transaction either entirely commits or entirely rolls back.
  • Consistency: no transaction can leave the database in an inconsistent state.
  • Isolation: A transaction cannot see other transactions in progress.
  • Durability: sufficient "nines" of probability that the database will lose no committed transactions.
