Anyway, the title is Executing, Configuring and… Read more
A couple of weeks back I installed SQL Server 2016 on my personal machine, including SSAS Tabular. Yesterday I created a new Tabular model project in SQL Server Data Tools. When I had to choose where to locate the model – integrated or a server workspace – I got the… Read more
Recently I published an open-source course/workshop to learn Power BI Desktop. Fellow MVP Dan English (blog | twitter) gave me the excellent feedback that IMDB actually doesn’t like people scraping their website for data.

NOTE: the DAX presented in this blog post is written in my locale (nl-BE). This means that semicolons are used in the functions and lists instead of commas. Also, we use the comma as the decimal seperator. 0.95 (in the US) is 0,95 in my locale. A couple of well… Read more
UPDATE: I also published a blog post using a DAX only approach. Check it out here.
Recently someone had a question if it was possible to change the color of a shape depending on the value of a measure. Imagine for example a dashboard with the picture of a… Read more

First a little background. I’m working on a large fact table that behaves itself as a slowly changing type 2 dimension. Weird right? But I have a good reason for this: it’s a snapshot table and if I would create the snapshots like you’re supposed to (by exploding the fact… Read more
I recently had to install SQL Server 2016 again on my Windows 10 machine. This also meant that I had to install and configure MDS as well. Last time it didn’t went so smoothly: Master Data Services error – Cannot read configuration file due to insufficient permissions. However, this… Read more
