From http://databases.about.com/od/specificproducts/a/acid.htm
- 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.
