Why Data Models and DAX patterns?

A pattern is a general reusable solution to a commonly occurring problem. Proven DAX patterns leverage immense experience across many industries and set a quality expectation. Obviously real DAX skills are still essential to adapting these patterns to new applications.

The ideal Data Models for Power BI and DAX patterns are closely related. DAX formulae are the simplest to author and easiest to understand when the data has been shaped into the ideal data model.

I developed the live examples below in Power BI; the original examples were only available in Excel.
