About the Course

SQL is among the top skills (if not the most important) required for data jobs. It’s widely used by data analysts, data scientists, and data engineers to read, extract, transform, clean, and prepare data for analytics.

SQL is a declarative programming language which means you say what you want without having to say how to do it. It’s highly recommend as a first programming language to begin with for learners from non-tech background. After completing this self-paced SQL course, you will get comfortable with basic programming and gain confidence to move on to other languages such as Python.

This course prepares learners for WeCloudData’s Data Bootcamps:

If you prefer to learn in a live environment, you can also check out WeClouddata’s Data Fundamentals course.

Celio Oliveira, Lead Data Scientist

This program is fantastic! I didn’t have a coding background and the way they prepared each module made it easier to understand from basic concepts to Advanced SQL and Python for Data Science that I just finished. There are still 4 modules to go before I become a Data Scientist but it is all very exciting. They really do prepare you and offer great support (includes problem sets, individually and in group and quizzes). The teachers are well connected and help you, no matter the prior experience. When you graduate, you graduate with a portfolio of projects a very good understanding academically and also hands on practise what is important as they showcase your writing capability.
