ACID properties define how a database maintains reliability.
ACID stands for Atomicity, Consistency, Isolation, and Durability.
These properties protect data during transactions.
Atomicity ensures that all operations in a transaction are completed successfully or none are applied.
Partial execution is not allowed.
Consistency ensures that the database moves from one valid state to another valid state.
All rules and constraints are maintained.
Isolation ensures that transactions do not interfere with each other during execution.
Durability ensures committed data is never lost, even after system failure.
ACID properties are the foundation of reliable databases.
They are critical for banking, finance, and enterprise systems.
Understanding ACID is mandatory for backend developers.
