🗄️ MySQL Foundations: Master the World's Most Popular Database

Learn MySQL from scratch. By the end of this course, you'll be creating databases, writing powerful queries, designing table relationships, and managing data like a pro.

📚 About This Course

This course teaches you MySQL — the world's most widely used open-source relational database — from the ground up. No prior database experience required. You'll start by understanding what databases are and why they matter, install MySQL on your own machine, and progressively learn everything from simple queries to multi-table joins, database design, transactions, and security.

Every lesson builds on the last with hands-on exercises using real data. By Module 4 you'll be writing complex multi-table queries, and by the end you'll understand how to design, optimize, secure, and back up production-quality databases. This course is the first step in a learning path that continues with PHP Foundations and PHP & WordPress.

What You'll Learn

How relational databases work — tables, rows, columns, and SQL
How to create databases, define tables, and enforce data integrity with constraints
How to write queries — filtering, sorting, aggregating, and joining data across tables
How to design normalized database schemas with proper relationships
How to use indexes, views, stored procedures, and transactions
How to manage users, permissions, backups, and imports/exports

Who This Course Is For

Complete beginners with no database experience
Web developers who want to understand the data layer
Students preparing for PHP, Python, or JavaScript backend development
Anyone who works with data and wants to learn SQL

Learning Path

This course is Part 1 of a three-course sequence:

MySQL Foundations (this course) — Database fundamentals and SQL

📖 Course Modules

Module 1: Getting Started

Meet MySQL, install it on your machine, and run your very first queries from the command line and phpMyAdmin.

Module 2: Tables & Data Types

Create tables, define columns with the right data types, set up constraints, and perform basic CRUD operations.

Module 3: Querying Data

Filter, sort, aggregate, and nest queries to extract exactly the data you need from any table.

Module 4: Relationships & Joins

Connect tables together with foreign keys and write multi-table queries using every type of join.

Module 5: Database Design

Optimize queries with indexes, simplify access with views, and design properly normalized schemas.

Module 6: Advanced Features

Encapsulate logic with stored procedures, protect data with transactions, and lock down access with user permissions.

Module 7: Real-World Skills

Import and export data, back up your databases, and plan your next steps into PHP and beyond.
