Learn how SQL works — and why understanding it is crucial before diving into SQL injection.

In this beginner-friendly video, we break down how SQL communicates with databases, how commands like SELECT, INSERT, UPDATE, and DELETE work, and how user input becomes part of a query in a web app. Using a real-world example of an online bookstore, we walk through common SQL operations and set the stage for understanding SQL injection in the next video.
