Course overview

In this course, you’ll learn concepts such as the different types of joins and how to combine joins with subqueries to answer business questions. You’ll also learn how to write queries using three or more tables, how to perform recursive joins and pattern matching, and how to control how the data will look with CASE statements.

As you progress, you’ll learn how to build and organize complex queries to make them more readable using the WITH clause, and how to use set operations such as UNION, UNION ALL, EXCEPT, and INTERSECT to combine tables. You’ll also learn relational database concepts such as normalizing a table, designing and creating a database, and more.

Best of all, you’ll learn by doing — you’ll practice and get feedback directly in the browser. At the end of the course, you will complete two guided projects:

  • The SQL data analysis workflow
  • Designing and creating a database
