Wonder how databases work? Every time you order food, log into an app, or connect with someone on LinkedIn, a database is working behind the scenes to store and retrieve your data in milliseconds. But how does it really work?

In this beginner-friendly video, Dhananjay from Zepto explain how modern databases structure information using tables, keys, indexes, and queries. You'll learn how data is organised in rows and columns, what happens during a read/write operation, and why some databases are faster than others.

We also touch on how relational databases ensure consistency using rules like ACID, and where SQL fits in as the language that helps you communicate with these systems. Whether you're completely new to tech or just curious about backend systems, this is the perfect starting point to understand the backbone of digital apps. This is also part of the Newton Launchpad SQL Learning Series, a free, beginner-first platform by Newton School that helps you go from "What is a database?" to "I can write my own SQL queries."
