ACID properties

Question

ACID properties

Accepted Answer

ACID properties ensure database transactions are reliable and consistent.

ACID stands for Atomicity, Consistency, Isolation, and Durability.
Atomicity ensures that a transaction is treated as a single, indivisible unit of work.
Consistency ensures that a transaction brings the database from one valid state to another.
Isolation ensures that concurrent transactions do not interfere with each other.
Durability ensures that once a transaction is committed, it will remain committed even in the face of power loss or other failures.
For example, if a bank transfer involves deducting money from one account and adding it to another, the transaction must be atomic to ensure that the money is not lost or duplicated.
ACID properties are important for mission-critical applications such as financial systems and airline reservations.
