PostgreSQL Exercises: Learn SQL and PostgreSQL Through Interactive Exercises

PostgreSQL Exercises is an open-source web application that helps users learn SQL and PostgreSQL through interactive exercises and quizzes. It covers basics like SELECT queries as well as more advanced topics like window functions.

What is PostgreSQL Exercises?

PostgreSQL Exercises is an open-source web application designed to help users learn SQL and the PostgreSQL database system. It features over 200 interactive exercises focused on teaching concepts ranging from basic SELECT queries to more advanced topics like joins, subqueries, and window functions.

The application provides an easy-to-use interface where users can write, execute, and test their SQL queries against preset database tables. It offers real-time feedback on whether queries are correct or not, allowing users to iterate and improve their skills. As you solve more exercises correctly, you progress through different difficulty levels on your way to SQL mastery.

Beyond interactive lessons, PostgreSQL Exercises also features quizzes, a syntax guide, and explanations for each database concept covered. The quizzes evaluate your learning by having you solve SQL problems without any hints or feedback until the end. The syntax guide serves as a helpful reference for PostgreSQL functionality. And the concept explanations provide clear, beginner-friendly descriptions accompanied by illustrative examples.

By engaging users in a hands-on, practical manner, PostgreSQL Exercises aims to help people not only learn SQL but retain that knowledge for applying it in real environments. As an open-source project, the application focuses on depth over breadth in the belief that mastering core database skills leads to better understanding. Whether you're preparing for an interview or just interested in databases, PostgreSQL Exercises is an excellent way to progress your skills.
