Thanks to SQL, you can easily extract data from a database and create an SQL report. What for? To draw appropriate conclusions from and base strategic decisions for your organization on data. It can also be the basis for plans for your next campaign or investment. The possibilities of data analysis are endless.

SQL is essential for data analysts, data scientists, financial analysts, software engineers, marketers, and even managers who need to make data-based decisions. Check out how SQL can help you democratize data in your organization!

But even advanced SQL students and professional programmers and developers will find something for themselves. For example, we humbly say we offer the best Window Functions course on the market. Check it out!

How Long Does it Take to Complete This Track?

It all depends on how motivated you are to learn SQL. By our estimates, it shouldn't take you more than 84 hours to complete all 7 courses. That’s a lot of material for the reasonable amount of effort required – there are over 880 interactive SQL exercises.

But we do not advise you to try to do all the courses at once. You should acquire practical SQL knowledge and skills gradually to ensure the most effective learning experience. We recommend spacing the courses over at least two or three months to let the knowledge sink in. It could look like this:

• Month 1. Complete 3 courses (36 hours): SQL Basics, HHow to INSERT, UPDATE, and DELETE Data in SQL, and Standard SQL Functions. Use our SQL Monthly Challenges to practice your knowledge.
• Month 2. Complete the Creating Basic SQL Reports and Window Functions courses (30 hours).
• Month 3. Complete Recursive Queries and GROUP BY Extensions in SQL (25 hours).
