Building DAX models

“

- [Instructor] Within our Power BI semantic model, DAX plays an important role in helping us build the calculations that we want. DAX, short for data analysis expressions, is a language that enables us to create formulas with functions, operators, and values for building advanced calculations within our tabular data model. DAX formulas produce tables, columns, and measures as their outputs from the input formulas that we put into them. In particular, DAX measures are one of the most important and impactful ways to build more advanced models in Power BI. Measures are portable dynamic DAX calculation formulas whose results change depending on the filter context in which we're evaluating them. I recommend trying to organize your measures within your semantic model. I'm going to do this by creating a measures group. We'll do so by entering data into our model in a blank table. We'll rename this new table calculations, and load it without anything other than the blank column one field into…
