About this course

This course is intended for business users who have been using Power BI to build analytic solutions and are ready to take advantage of the power and flexibility that DAX provides. Learning DAX is a very common “next step” for experienced Power BI users.

Overview

At course completion, you should be able to

Describe DAX syntax, data types, and errors
Use DAX to create calculated columns, measures, and tables
Explain how DAX calculations are evaluated, along with the differences between row context and filter context
Configure and use Time Intelligence to perform common time-based calculations, for example to-date calculations, year-over-year analysis, moving averages, etc.
Create calculated columns and measures that use data from multiple tables in the data model
Write measures that handle error conditions gracefully
Use DAX to enhance the Power BI user experience
Use DAX Studio to connect to a Power BI data model and execute simple queries

Description

Welcome to Introduction to DAX for Power BI. This two-day instructor-led course is intended for business users who have been using Power BI and want to use DAX to create custom calculations in their data models. In this class, you will be introduced to using Data Analysis Expressions (DAX), which is the expression language that is used to create custom calculations in the Power BI Data model. The course covers some of the theoretical underpinnings of the data model and the DAX language, but the emphasis is on using DAX to solve common business problems. You will learn how to write your own calculated columns, measures, and tables, how to visualize the way Power BI computes DAX calculations, and how to troubleshoot custom code.

What people say about us

Booking process was very easy. Once initial contact was made everything happened smoothly.

Great course yesterday and can’t give enough amazing feedback for John. I’ve never had a teacher hold attention of a class from start to finish, but yesterday he did this.

Alan delivered the training in an easy to understand and pleasant manner which was broken down into manageable chunks with an appropriate number of breaks to give folk time away from their laptops and screens. It is never easy to do 2 days of training on a fairly in-depth subject involving Software even in a classroom environment and remaining focused and engaged so doing it remotely adds another level of complexity, but I have to say that personally this was one of the best Training Events that I have attended for some years. I have gained so much knowledge of MS Project and it will certainly make my job easier going forward.

A large part of what I gained has to be credited to Alan’s manner and delivery and I should be grateful if you could pass on my thanks to him.

Also, the support, together with joining instructions & training literature etc from Nexus Human has been excellent – thank you for that. I intend feeding that back to our People and ICT Teams too

This is the 3rd course I have done with Arun. He is very helpful and always supportive if I have other questions outside the lecture parameters. I have already recommended him and Nexus Human to work colleges and would do so again after this course.

The instructor was excellent. Was willing to field any questions we had and deal with our specific queries.

The class just finished and I just wanted to mention to you that it was absolutely amazing. The quality of the training had very high standards, the trainer explained amazingly well and we actually practiced (did) all the steps. It was not learning by watching a presentation but by actually doing. The training has been delivered from Atlanta (US) and I cannot wait to go tomorrow in the office and recommend it. The connection and the lab environment were running perfectly.
Once again thank you very much and looking forward for the next trainings scheduled. Enrolling via Nexus Human was the perfect choice.

Sharon was lovely and has a fantastic knowledge. Honestly I didn't think I needed part 1 but I am SO glad I came. Thank you. Will be back in for part 2.

Nexus Human Student

Excellent interaction and answered all of my questions. Looking forward to being able to apply some of the tips and features learned today which hopefully should have real impact on some of the more time consuming tasks currently encountered.
