Concurrency control in transaction.

Ever wondered how thousands of people can book a seat on the same flight at the same time without the system breaking? That’s the magic of Concurrency Control. In this video, we dive deep into how databases manage simultaneous transactions to ensure data integrity and prevent the dreaded "lost update." We break down the two most critical tools in a developer's arsenal: Shared (S) Locks and Exclusive (X) Locks. 🔍 What’s Inside? The Problem: Why we need concurrency control (Dirty Reads, Unrepeatable Reads). Shared Locks (Read Locks): How to let multiple people view data without letting anyone change it. Write Locks (Exclusive Locks): The "Do Not Disturb" sign of the database world.
