Course Overview
Get business insights from your SQL database
Many of us know a bit of SQL. But when it comes to answering real-world business questions, our rusty memories of database classes let us down!
This video course will take you to an intermediate level of familiarity with SQL in the context of writing maintainable and sophisticated SQL for specific business queries. You will start by importing our first dataset which will be the DVD rental database. We then will explore and put into practice various SQL clauses and Join types. All examples of fundamental concepts are tightly guided by practical and hands-on exercises. No “Foo Bar” allowed anywhere, just problems from the wild, brought into the educational space. You will also learn tricks to get external data into the database, without worrying excessively about DBA functions and considerations.
You’ll also find out how to take the data into popular BI tools (Excel and Tableau) and refine the analysis further while discussing the interpretation of the data. By the end of the course, you will have developed your SQL skills and learnt how to answer business questions from the set of data.

Each chapter start with a question. I would pause a video and try to solve it for 5 minutes before watching. It's a very good introduction course.

Great course, concise, but the quizzes are extremely basic.

I felt that the course was great for real-world application, I did feel however that the instructor went through it rather quickly and could have slowed it down a bit. I also feel the course was of a high quality and would have given it a better rating but felt it was rather short in length
