If you are relative beginner in Power BI / Business Intelligence, you will definitely benefit from this lab/tutorial. First, I go over the best practices with respect to designing your data model. I define dimensions and facts and why not thinking about the layout of your data leads to really bad model designs. After theory, I go through all the steps in the Star Schema lab (and then some) to make sure that you will have good understanding of all the steps in the lab. All lab materials can be downloaded here:
I recommend that you watch the video first and you can either follow along and pause me so you can repeat all the lab steps right after me or listen to the entire thing and try to run through the lab on your own. This is one of the most important labs that I teach, it has been taken by thousands of students now and it’s always done a good job of explaining how to think of your data and also how to turn your data into facts and dimensions. Enjoy!
