In database transactions, what does ACID stand for?

Step 1: Understand that ACID is an acronym used in database transactions.
Step 2: Learn what each letter in ACID stands for:
Step 3: 'A' stands for Atomicity, which means that a transaction is all or nothing.
Step 4: 'C' stands for Consistency, which ensures that a transaction brings the database from one valid state to another.
Step 5: 'I' stands for Isolation, which means that transactions occur independently without interference.
Step 6: 'D' stands for Durability, which guarantees that once a transaction is committed, it will remain so, even in case of a system failure.

Atomicity – Ensures that all operations in a transaction are completed successfully or none at all.
Consistency – Guarantees that a transaction will bring the database from one valid state to another, maintaining all predefined rules.
Isolation – Ensures that transactions are executed in isolation from one another, preventing concurrent transactions from affecting each other.
Durability – Ensures that once a transaction has been committed, it will remain so, even in the event of a system failure.
