One of the powerful features of the Tabular data model is to extend the model by adding calculated columns and measures. Both objects are defined using DAX, but besides this similarity, they are entirely different beasts. Here you will find guidance when to use what!
Data modeling and understanding the physical layer are comparable with being a good driver and a good car mechanic. It's unnecessary to excel in both areas. Still, it helps tremendously when driving an F1 car through uncharted terrain if there is some understanding of how an F1 car works if repair becomes necessary.,
Before we delve into the realm of Power BI data modeling (or Analysis Services Tabular), it's necessary to understand what this data modeling is all about. A thorough understanding of data modeling is vital because the Power BI data model determines the insights that can be derived and visualized from our data, leading us to better and more actionable decisions. Because we are striving for the ideal data model all the time, others call us obsessed with data modeling 😊 To get this...
This post shows how a dynamic member called Other can be used for Data Visualizations in Power BI in addition to the common requirement of the visualization of the TOP N or BOTTOM N members. A solution is used that utilizes a combination of data modeling and DAX.
