Part 1 of this post included my favourite resources for Microsoft’s Power BI exam (70-778) when it comes to the first two skills measured. This time I will cover more resources for data modelling and DAX, with maybe the most precious one when it comes to these. Then, I will talk about the third measured skill i.e. “Configure Dashboards, Reports and Apps in the Power BI Service”. Next, I will share 5 tips which helped me while actually taking the exam. Finally, those who just get started with Power BI can get some hints where to go from here at the end of this post.[Read more…] about Preparing for Analyzing and Visualizing Data with Power BI (Microsoft Exam 70-778) – Part 2

Subsequently measures can be defined to grow this important fundament for the effective use of data.
My blog’s category “Dear Power BI” is all about charts and visualisations created using Microsoft Power BI. Here you can use Power BI to explore the development of your favourite German Bundesliga club’s goal difference (GD) until matchday 15 in the current season (2018/ 19).[Read more…] about Dear Power BI…development of German Bundesliga clubs’ goal differences
