This two-day workshop is a complete course about optimizing queries and measures in the DAX language. DAX is the native language of Power Pivot for Excel, Power BI Desktop and SSAS Tabular models in Microsoft SQL Server Analysis Services. This course is aimed at BI professionals, Power BI and Excel users who already know the DAX language and want to learn how to optimize DAX formulas and models for improving performance.
The goal of the 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. All the attendees will receive a copy of the book The Definitive Guide to DAX.
The course includes hands-on labs: you will make practice using your own notebook.
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 participating to the Mastering DAX Workshop, or having an equivalent real-world experience. Use the self-assessment test to check your DAX expertise.
