📘 Introduction

A database is an organized collection of data that can be easily accessed, managed, and updated. In web development, databases play a central role in storing information such as user accounts, products, posts, messages, and more. Whenever a user registers, logs in, or interacts with a website, data is usually stored or retrieved from a database.

Databases are essential for dynamic websites and web applications, where data is not hardcoded into the web pages but served from a backend system depending on the user’s actions.
