The Importance of Star Schemas in Power BI

Paul Turley lays out facts (and dimensions):

There is no secret about this. If you do any legitimate research about Power BI (reading blogs, books or training from reliable sources), you will quickly learn that a lot of basic functionality requires a dimensional model, aka “Star Schema”. This is a hard fact that every expert promotes, and self-taught data analysts either have learned or will learn through experience. So, if everyone agrees on this point, why do so many resist this advice?

Perspective is everything. I didn’t understand why getting to the star schema was so out of reach so often until I was able to see it from another perspective. There are a few common scenarios that draw source data into different directions than an ideal dimensional model.

Read on for Paul’s take on the subject.
