Optimizing DAX Video Course

This is the video course version of the Optimizing DAX workshop. It teaches you how to optimize queries and measures in DAX.

DAX is the native language of Power Pivot for Excel, Power BI Desktop and SSAS Tabular models in Microsoft SQL Server Analysis Services. This video course is aimed at users of Power BI, Power Pivot, and at Analysis Services developers who already know the DAX language and want to learn how to optimize DAX formulas and models for improving performance.

The goal of the video course is to enable you to find bottlenecks in DAX calculations using tools such as Profiler and DAX Studio, providing the knowledge to improve the performance by using different DAX formulas or by changing the data model, when required. The video course is made up of over 10 hours of lectures, plus another estimated 8 hours of individual exercises. You can watch the videos at anytime and the system will keep track of your progress. Within the video course you can download the material for all the exercises.

Prerequisite: Attendees need a good knowledge of the DAX Language, and a previous experience using either Power Pivot for Excel, or Power BI Desktop, or Analysis Services Tabular. You may acquire this knowledge by following the Mastering DAX Workshop, or by having equivalent real-world experience.

Students have access to a private discussion area where they can interact with the instructors asking questions related to the lectures and the exercises.
