ACID properties are fundamental to database transactions. Atomicity ensures all operations in a transaction succeed or fail together. Consistency maintains data validity, Isolation prevents concurrent transaction interference, and Durability guarantees committed data persists even after system failure.
ACID stands for Atomicity (a transaction either fully completes or fully fails, with no partial effects), Consistency (a transaction takes the database from one valid state to another, respecting all rules/constraints), Isolation (concurrent transactions don't interfere with each other's intermediate states), and Durability (once committed, changes survive system failures). These four properties together define what makes a transaction reliable in a database system.
