Behind every powerful Power BI report is a layer most people never see: DAX queries. DAX (Data Analysis Expressions) is the formula language that turns raw data into accurate, meaningful measures. Here’s how DAX queries unlock your data’s full potential.
Beacon builds on Microsoft Power BI, the industry-leading analytics platform.
What DAX queries do
- Create custom measures and calculations
- Handle time intelligence (year-on-year, running totals)
- Filter and aggregate data intelligently
- Power the numbers behind every visual
Why DAX is worth getting right
Good DAX queries are the difference between a dashboard that’s merely pretty and one that’s accurate and fast. Poorly written DAX gives wrong numbers or slow reports – which is why we sweat the modelling and DAX behind every build.

Frequently asked questions
What are DAX queries used for?
DAX creates the custom measures and calculations behind Power BI visuals – from simple totals to advanced time intelligence.
Do I need to learn DAX myself?
Not necessarily. For accurate, fast reports, many businesses have us build the DAX and data model, then drive the dashboards themselves.
