What you'll learn:
- Understand how relational databases work
- Write SQL queries to retrieve and filter data
- Use WHERE, ORDER BY, and LIMIT effectively
- Combine data from multiple tables using JOINs
- Summarise data with aggregates (COUNT, SUM, AVG)
- Use subqueries and nested queries
- Insert, update, and delete records safely
- Improve performance using indexes
- Apply SQL skills in a practical final project
SQL is one of the most in-demand skills for working with data — but getting started often means installing servers, configuring databases, or paying for cloud tools.
This course removes those barriers.
In Practical SQL with SQLite, you’ll learn how to query, analyze, and manage data using standard SQL, while working entirely with free, lightweight tools that run on your own computer.
You’ll start with the fundamentals and quickly move into writing real queries, working with multiple tables, aggregating data, and improving query performance. Every concept is demonstrated with hands-on examples, so you learn by doing — not by memorising syntax.
SQLite is used throughout the course because it is simple, fast, and widely used in real applications, from mobile apps to embedded systems. The SQL skills you learn here transfer directly to MySQL, PostgreSQL, and SQL Server.
By the end of the course, you’ll be comfortable writing practical SQL queries and working with databases confidently — without installing complex software or using paid platforms.
