About the Course
This 2-Day course is designed to lay solid foundations before diving deep into complex DAX functions. This is achieved by focusing on 2 key elements i.e. engagement, and practicality. Participants will be spending their time writing hands-on DAX functions, looking at the result, discussing what works, and especially what does not work and WHY? Additionally, all the modules and concepts are reinforced by real-life, scenario-based examples to solidify the learnings.
After this course, participants should be able to write DAX expressions to address their specific business needs, leverage available resources to tackle complex problems, debug and optimize using available tools and the right techniques. Moreover, the entire course walks through a single data set so participants can concentrate on mastering the concepts rather than worrying about the specifics of the dataset.
Who should do this course?
This course is for business users (Finance, Marketing, Operations etc.) or SQL Server report creators who want to take their reports and dashboards to a next level by writing custom calculations using DAX functions to address specific business requirements.
Prerequisites
This DAX course is suitable for people who have either completed the Power BI essentials course or have a reasonable understanding of data modeling concepts. To benefit most from this course, participants must have some expertise in using excel functions or SQL.

Course Reviews
(4.90 out of 5) Claudia B [ 22 September, 2021 ]
- This was a great course with an excellent coverage of the Essentials for DAX language use.
- Specifically for me it was great as it helped me to understand more clearly and deeply how DAX functions works, and all related to filter context, row context and context transition while using calculated columns and calculated measures which are the core of every single and useful model.
- It helped me to expand my knowledge as it broad up many useful functions to be use in real scenarios.
- The instructor was excellent. He was the key on us to understand most of the concepts by his patient and the way to approach each pf the topics we touch base during the course.
(5.00 out of 5) Michele S [ 09 September, 2021 ]
The pace was good and the instructor was very responsive and knowledgeable when asked additional questions.
I was a bit brain dead by the end of the day.
I feel a bit more confident to get into creating measure and improving my reporting.
(4.90 out of 5) Darlius K [ 09 September, 2021 ]
The course was run well online by Adam who did an exceptional job pacing the topics and teaching us the course content. His understanding was sound and did well to explain what Power BI could do, as well as it's limitations from a DAX perspective. I appreciated his willingness to discuss some topics in greater detail to round out the discussion, which he was happy to engage in.
(4.90 out of 5) Vladimir V [ 22 July, 2021 ]
Course provided a number of beneficial strategies to take back to the existing work I do. Adam was very enthusiastic and engaging as a presenter, and was able to explain the logic and demonstrate through examples, hot to achieve the desired result from each function. Well paced delivery of content.
