ACID Properties in Database Management System

ACID properties are essential characteristics that guarantee the correctness and reliability of transactions in a database management system. ACID stands for Atomicity, Consistency, Isolation, and Durability.

Atomicity

Atomicity ensures that all operations within a transaction are treated as a single unit of work. Either all operations are successfully completed, or none are applied to the database.

Consistency

Consistency ensures that the database remains in a consistent state before and after the transaction. It enforces all constraints and rules defined in the database schema.

Isolation

Isolation ensures that each transaction is isolated from other concurrent transactions. It prevents interference between transactions and maintains data integrity.

Durability

Durability guarantees that once a transaction is committed, its changes are permanently saved in the database, even in the event of system failure.

Understanding and implementing the ACID properties are crucial for maintaining data integrity and reliability in a database management system.
