📊 SQL Introduction

SQL (Structured Query Language) is the universal language for working with databases. It lets you create, query, update, and manage relational databases like MySQL, PostgreSQL, and SQLite.

💾 SQL Setup & Compilers

To start running SQL queries locally or online, you can use:

MySQL Workbench (GUI for MySQL databases)
SQLite Browser (lightweight local SQL database)
Online SQL editors like SQLiteOnline.com or DB-Fiddle

🖼️ Setup Screens

💡 Tip: No server setup needed if you use SQLite — just download the browser app and start practicing.

🔧 How This Query Works

SELECT name, age — fetches the name and age columns
FROM users — specifies the users table
WHERE age > 25 — filters records where age is greater than 25
