This lecture contains a downloadable ZIP file with all of the CSV data files you’ll need for the upcoming sections of the course.
Please download the ZIP file and extract the contents before continuing, as we’ll be using these CSV files in later lessons.
You may also notice a Power BI (.pbix) file included in the download. You can ignore this for now — we’ll come back to it later in the course when it becomes relevant.
All retail sales CSV files should be placed together in one folder called Retail_Sales
The retail products file should be placed in its own folder called Retail_Products
The retail stores file should also be placed in its own folder called Retail_Stores
Keeping this folder structure consistent is important for later sections of the course.
Course Description
This Power BI course is designed to teach you exactly what you need to know to start using and become effective with Power BI. You will learn how to build professional Power BI dashboards built and designed to Pro Standards.
Rather than simply showing you which buttons to click, this course focuses on understanding how Power BI works, what that enables you to do, and how those capabilities fit into a clear, repeatable Power BI dashboard development process.
By the end of this course you will be able to build dashboards confidently on your own, adapt to new datasets, and solve real business intelligence problems independently, instead of relying on pre recorded step by step walkthroughs.
This is an accelerated Power BI beginner to intermediate course, designed to reflect how Power BI is actually used in real organisations.

What students say about my teaching style
I have helped thousands of learners understand Power BI through my YouTube content, and the feedback consistently highlights clarity structure and real world understanding.
"Wow wow wow. I am just flabbergasted by your teaching. Thank you."
Ahmed R.
"This was super helpful for me in understanding dimensions and dimension tables."
Daniel P.
"Great work. You made this look so easy."
Sarah L.
"Excellent teaching. Great explanations and very easy to follow."
Michael T.
"Straight to the point thank you."
James K.
"Incredible video I really enjoyed it. Muchas gracias."
Carlos M.
"Building a dashboard is a bit like art. You can be taught how to hold a brush and learn the basic strokes, but that alone does not mean you will create great or effective art. Power BI works in a similar way. Learning where the buttons are is useful and we will do that, but understanding how to apply techniques and design choices is what leads to meaningful effective dashboards."
By the end of this Power BI dashboard course
You will not just know how to create reports. You will understand how to think in Power BI, how to structure your models, and how to design dashboards that genuinely support business decision making.
If you are looking for a Power BI course that teaches you how to think, not just follow instructions, this course is designed for you.
