ACID is the acronym for four features, namely,
- Atomicity
- Consistency
- Isolation
- Durability
Atomicity
- An operation is either fully completed or else is considered as incomplete.
Consistency
- A database must remain in a consistent state after a transaction.
Isolation
- When more than transaction is taking place in parallel, the transactions should not affect each other.
Durability
- The database should be durable enough to hold all the transactions.
