What is MySQL? A Complete Beginner's Guide

MySQL is the world's most popular open-source relational database management system (RDBMS). It stores data in structured tables and lets you retrieve, filter, and analyse that data using SQL (Structured Query Language). From e-commerce giants to startups, millions of applications rely on MySQL to manage everything from customer records to sales transactions.
