What is ACID?

ACID stands for four key database transaction properties: Atomicity (all-or-nothing execution), Consistency (valid state maintenance), Isolation (concurrent transaction separation), and Durability (permanent commit survival). These principles ensure reliable data processing and integrity in database systems, which are crucial for financial and e-commerce applications.
