Peter van den Bos
Peter van den Bos is a Business Intelligence Consultant, speaker, and founder of Dutch BI Geek. For over a decade, he has helped organizations get a better grip on their data – making Power BI not just look good, but also run fast and make sense. With deep expertise in data modeling and DAX, Peter has a talent for explaining complex topics clearly and with energy.
He shares his insights through blogs, vlogs, and training sessions, always with one goal in mind: helping others make better, smarter decisions with data. Expect practical tips, performance tweaks, and well-grounded advice – straight from the field. His sessions are a favorite among controllers, analysts, and BI professionals who want to understand what’s really going on under the hood.
When he’s not training or presenting, you’ll find him tweaking data models just for fun, deliberately slowing down DAX queries (so he can fix them), or stress-testing visualizations like it’s a competitive sport. His Dutch-language YouTube channel is a playground for anyone with a passion for Power BI – or anyone ready to embrace their inner data nerd.
Peter van den Bos's Sessions
Incremental Refresh Power BISQLBits 2026
Incremental refresh is essential when Power BI data models grow beyond simple full refreshes. In this session, we’ll look at how incremental refresh works in Power BI, how to set it up correctly, and how to avoid common pitfalls. The focus is on practical guidance, testing strategies, and building a refresh process that remains predictable and performant as data volumes increase.
Modeling Power BI with Code: Unlocking the Power of Semantic LinkSQLBits 2026
Learn how to build and manage Power BI semantic models using code with Semantic Link. This hands-on session shows how to load data, explore models, and create measures, tables, and relationships programmatically using notebooks.
Optimising Power BI Performance Through Data ModelingSQLBits 2026
Learn how a well-designed data model can significantly improve Power BI performance and simplify DAX. This session explains the key modeling principles that help you build faster, more efficient, and easier-to-maintain reports.
Practical Data Modeling in Power BI: Beyond the Star SchemaSQLBits 2026
This session explores practical data modeling techniques in Power BI beyond the classic star schema. You’ll learn how to make informed design choices for fact tables, work with snapshot data and SCD Type 2 dimensions, and handle many-to-many relationships using real-world scenarios rather than idealized examples.
Unlocking the Power of the VertiPaq Engine: Data Modeling for Maximum PerformanceSQLBits 2026
VertiPaq is the engine behind Power BI performance, but its behavior is strongly influenced by data model design. This session explains how VertiPaq stores and processes data, and shows how targeted modeling choices can significantly improve compression, memory usage, and query performance.
Optimizing Power BI: Enhancing Performance Through Data ModelingSQLBits 2025
Learn how to optimize your Power BI dashboards by building robust data models. Discover key foundations, pros and cons of different models, and techniques to simplify DAX formulas. Boost performance, reduce complexity, and apply insights to your daily work!
