====== Transactions ======


Transactions ensure data integrity by treating multiple SQL statements as a single unit.

**Example: Using Transactions**

<code>
START TRANSACTION;
UPDATE employees SET salary = 75000 WHERE id = 1;
COMMIT;
</code>

**Example: Rolling Back a Transaction**

<code>
START TRANSACTION;
DELETE FROM employees WHERE id = 2;
ROLLBACK;
</code>
