Because my Windows machine apparently decides to install updates over night (and thus reboot my machine), it has happened that I lost the query that I was writing for Redshift in the tool DBeaver. When you work with SQL Server Management Studio (SSMS), you typically don’t have this issue as a temporary copy is always […]
Star Schema Merchandising Available
Those of you who follow me on social media (twitter | LinkedIn | mastadon) or who read my blog here, might be familiar with my catchphrase “STAR SCHEMA ALL THE THINGS”. This slogan originated a couple of years ago when I had to convince some people that the star schema (aka the dimensional model) should […]
Book Review – SQL Query Design Patterns and Best Practices
Disclaimer: The publisher – Packt – sent me a free copy of the book for the intended purpose of a review. At the time of writing, the book is yet to be released (the date is set at the 22nd of March 2023). The book SQL Query Design Patterns and Best Practices: A practical guide […]
Reading AFAS REST API Data with Azure Logic Apps
Recently I had to read some REST API data using an Azure Logic App. The data itself comes from AFAS, a Dutch SaaS ERP company. In general, the process is mostly the same as reading the data with Azure Data Factory (check out this blog post to learn more): There’s a minor difference in how […]

Techorama is one of the biggest Microsoft-focused events in the European mainland, and it’s always a pleasure to be there. It’s organization is amazing and there are tons of interesting sessions.

Build Once – Add Metadata (the importance of metadata-driven frameworks)
When working in business intelligence, data engineering or data in general, there are some “mantras” that are being adopted by the larger community as “best practices”. For example, I shout “STAR SCHEMA ALL THE THINGS” anywhere I can, because a star schema is the most optimal way to design your model in Power BI. We […]
Why Managed Identities are Awesome
For the first workdays of this new year, I had the pleasurable task of resetting a bunch of passwords. The passwords belong to Azure AD users, service principals, SQL Server users etc. and all of these are tied into the ETL process of a data warehouse. Some are used to connect to source data, others […]
CONCAT_WS Function Truncates Text
I was writing some dynamic SQL that generates some SQL statements to load my facts and dimensions into a data warehouse. Some of those SQL statements can become very long, for example if a dimension has a lot of columns. When debugging, I noticed a couple of statements failing with various errors. Turns out, they […]
Allow a user to only trigger pipelines in Azure Data Factory
Typically you have a bunch of pipelines that are started by one or more triggers. Sometimes, a pipeline needs to be manually triggered. For example, when the finance department is closing the fiscal year, they probably want to run the ETL pipeline a couple of times on-demand, to make sure their latest changes are reflected […]
