Notes and articles on data, Power BI, DAX, and building reporting you can trust.
Stop patching Power BI reports with endless DAX and custom workarounds. A well-designed semantic model puts business logic where it belongs and makes BI more reliable, consistent, and easier to scale.
Read →The second edition of Mastering DAX in Power BI is coming soon. Alongside practical solutions for real data problems, the updated book explores how to utilise artificial intelligence to elevate your analytics.
