This post is a follow up to my first article regarding the above- referenced subject, in which I committed to Advance my Data Analysis EXpressions (DAX) in Power BI in my preparation for Exam DA-100: Analyzing Data with Microsoft Power BI as part of Microsoft Certified: Data Analyst Associate. True to my commitment, I completed a thrilling Udemy Course: Advanced DAX for Microsoft Power BI Desktop by Maven Analytics. I realized that there is a lot in the DAX language, (which I will not go into detail in this space). DAX like any other language needs constant practice, hence this not my end of my DAX learning, but just the beginning. I will continue revisiting this course and and other materials. As DAX is not only for Power BI, but also for SQL Analysis Services and Power Pivot in Excel data models, if time permits, in future I might as well study the Microsoft Excel: Business Intelligence w/ Power Query & DAX from my Udemy library with over 50 courses , which I snapshot below. We all have impulsive purchasing habits, some stock shoes, cars, wine, etc. In my case, my impulsive purchasing habits are online - I subscribe to courses, software as a service and other online services without second thought.
