This article describes the process of how I solve complex DAX, of course there is some fancy DAX included.

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!
This article is about durations.
When we are looking at something like this: 2:00
We think, at least most of the people I know, an event that takes 2 hours.
But when we change the notation just a little to 2:00 AM, we think: Whoa, that’s early (or late, depending on the perspective, of course).

I tend to create tables using M or a combination of point-and-click and M, because these tables are treated as base tables if the model is refreshed and for this reason these tables will benefit from all the compression magic, whereas tables created using DAX are not that well compressed.
There is just one thing that is more satisfying than writing complex DAX measures, and that is avoiding complex DAX due to smart data modeling.
This article will provide a different approach to tackle a common requirement, determining the previous value given a current date.
A common search strategy has to combine multiple items with an AND instead of the default OR. This Power BI file contains two DAX measures solving a search operation with the fancy name: relational division
This blog provides an introdution into some universal truths, of course things like evaluation context, or data lineage will be mentioned

This article is the starting point of a series of articles that demonstrates how to navigate through tables inside a Tabular Model, from Microsoft Analysis Services Tabular, Power Pivot or Power BI using DAX

This post describes approaches how to virtual relationships between tables can be established using the DAX function TREATAS() and also approaches how to create physical relationships instead.
