ACID Properties
- Atomicity—The transaction is all or nothing.
- Consistency—All constraints and other data integrity rules have been adhered to, and all related objects (data pages, index pages) have been updated completely.
- Isolation—Each transaction is completely isolated from any other transaction. The actions of one transaction cannot be interfered with by the actions of a separate transaction.
- Durability—After a transaction is completed, its effects are permanently in place in the system.
