Learn SQL

SQL is the standard language for working with data stored in tables. In this course you will learn how to manage large datasets and analyze real data using SQL. The course covers working with databases using SQL, creating queries for tables, and building SQL projects. You will also learn how to use aggregate functions and work with multiple tables to combine data from different sources. The course is designed for beginners and takes about five hours to complete. It is self-paced and taught in English. A certificate is available upon finishing the course. There are no prerequisites, so you can start even if you have never used a database before.

This particular course takes a practical approach. Instead of starting with theory, you write SQL commands from the first exercise. The modules guide you through creating queries, filtering data, and using aggregate functions like COUNT and SUM. By the end you will have built a small SQL project that you can show in a portfolio. The stated outcome is that you will be able to pull and clean data ready for analysis or reporting.

At the end of the course you will be able to write basic SQL queries to extract data from a database. You will know how to filter results, sort data, and use aggregate functions to calculate totals. These skills are enough to start working with data in roles such as data analysis, reporting, or marketing analytics. If you need to work with more complex data structures or larger datasets, you may want to look at the advanced SQL courses listed on the site.

This course does not cover advanced topics such as stored procedures, triggers, or performance tuning. It is built for people who are new to databases. Learners who already know the basics may find the content too introductory. Those who want deeper coverage of a specific database system such as Oracle or Microsoft SQL Server may prefer the Udemy alternatives listed on this page.
