In this chapter, you'll write custom functions to create new tables and calculated columns.

DAX for creating tables and columns

Row vs. query vs. filter context

DAX for calculated tables and columns

Creating a date table

Calculated column for costs

Data cleaning with DAX

Connecting data from different tables

Setting up Data Models with DAX

In this chapter, you'll write custom functions to create calculated measures. You'll also get introduced to variables to make writing DAX functions more efficient.

Methods to create DAX measures

Advantages of explicit measures

DAX and Measures

Using variables

Basic statistical measures

Quick measures

Expand your DAX power with some commonly used DAX measures. This chapter focuses on filtering and counting functions.

Understanding different filter functions

Using different filters with DAX

Filter ALL the data

Calculating with a filter

Filtering and Counting with DAX

This chapter covers the core concept of  another powerful set of DAX functions, the so called iterating functions. You will explore iterations with exercises focusing on ranking and iterating your data.

Course Glossary

DAX, or Data Analysis eXpressions, is a formula language used in Microsoft Power BI to create calculated columns, measures, and custom tables. Once mastered, DAX gives you powerful control over visuals and reports, allowing for better performance and more flexibility. This course covers the core concepts such as row query and filter context, with exercises focusing on filtering, counting, ranking, and iterating functions.

DAX Functions in Power BI

Analista dati in Power BI

Returns all rows of a table, ignoring any filters.

Useful for clearing filters and performing calculations on all rows.

Returns a table based on a specified filter.

Used to override the cross-filtering between two tables.

Change the direction of a specified relationship to 'Both'.
