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.
This two-day workshop is a complete course about optimizing queries and measures in the DAX language.
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.
The course includes hands-on labs: you will make practice using your own notebook.
It is possible to extend the course to three days, using company data in order to extend the practice and optimize real-world workload of existing databases.
