MySQL Transactions and ACID Properties

Implement a Bank Transfer Transaction

Write a MySQL transaction that transfers funds between two accounts ensuring all ACID properties are met.

Expected output: A transaction that either completes both updates or rolls back on failure.

Hint: Use START TRANSACTION, UPDATE statements, and COMMIT or ROLLBACK.

Experiment with Isolation Levels

Test different MySQL transaction isolation levels and observe their effects on concurrent reads and writes.

Expected output: Understanding of how isolation levels affect transaction behavior.

Hint: Use SET TRANSACTION ISOLATION LEVEL and concurrent sessions.

Atomicity guarantees that all operations within a transaction are completed successfully as a single unit, or none are applied if any operation fails.

Isolation ensures that concurrent transactions do not interfere with each other's intermediate states, preventing issues like dirty reads or non-repeatable reads.

Durability ensures that once a transaction commits, its changes are permanently saved and will survive system crashes or failures.
