About the free online course

Knowing how to work with databases is a core skill in technology, whether you aim to become a developer, analyst, QA, or build your own product. This free online course helps you move from curiosity to confidence with MySQL, one of the most widely used relational database systems in the world. You will learn how databases are organized, why keys matter for data integrity, and how to set up a MySQL server so you can practice with a real environment from the start.

As you progress, you will gain the practical SQL abilities that employers and real projects rely on. You will learn how to explore a database, retrieve the information you need with SELECT, and apply rules that keep your statements clear and correct. From there, you will sharpen your query results by choosing the right columns, removing duplicates, limiting output, and sorting data to reveal patterns that are otherwise hidden.

The course also focuses on how to ask better questions of your data. You will practice filtering with WHERE, combining conditions with AND and OR, and using grouping logic that prevents mistakes. Searching becomes more powerful as you work with wildcards, pattern matching, and regular expressions to handle real-world text data. You will also learn to create custom outputs using expressions and functions, including aggregate functions that help summarize large datasets into meaningful insights.

To go beyond single tables, you will understand how to connect information properly using joins, including outer joins for scenarios where some records may not match. You will work with subqueries to solve questions step by step, and combine results using UNION when appropriate. You will also learn efficient approaches for searching text with full-text search features, a valuable skill for building search-driven applications.

Finally, you will strengthen your foundation in data manipulation and structure by practicing inserting, updating, and deleting records safely. You will understand how tables are created and modified with constraints such as NOT NULL and AUTO INCREMENT, and how to maintain a database over time using operations like alter, drop, and rename. The result is a solid MySQL toolkit you can apply immediately in projects, interviews, and everyday work with data.
