How to use relationships in Power BIand the differences between columns and measurements
LEUNG Chun Hei - HAESL
Course - Advanced Power BI: Data Modeling, DAX, and Enhanced Analytics
I was pleasantly surprised by the trainer's attitude toward the psychological aspects of the reporting activity, not just the technical ones. I believe the most valuable part of this course is that it showed me what excellence looks like in the field I have chosen, and that motivates me greatly. As for technical elements, it helped me the most to understand DAX concepts and how to incorporate them into my work.
