ACID Properties in RDBMS - Interview Question Answer

The ACID properties in RDBMS stand for Atomicity, Consistency, Isolation, and Durability. These properties are essential for ensuring the reliability and integrity of transactions in a relational database management system.

Atomicity: All operations in a transaction must be completed successfully, or none at all. This ensures that transactions are either executed completely or not at all.

Consistency: The database remains consistent before and after the transaction. Any changes made by a transaction should adhere to all the database constraints and rules.

Isolation: Transactions should be isolated from each other to prevent interference. This ensures that the concurrent execution of transactions does not affect the outcome.

Durability: Once a transaction is committed, its changes are permanent and will be preserved even in the event of a system failure. This guarantees that data remains consistent and reliable.
