Unity Catalog Metric Views, now in Power BI: one unified, governed semantic layer for all your reporting and AI

By · Published by Everything Blog

In short

The integration enables organizations to define metric views once in Databricks Unity Catalog and publish them directly into Microsoft Power BI semantic models. In this setup, metric views act as tables where dimensions map to columns and measures automatically convert into DAX measures without manual modeling. Users can trigger synchronization on demand via Catalog Explorer or schedule automated updates using Lakeflow Jobs. Furthermore, the architecture supports real-time querying on managed Delta tables through Lakehouse//RT and DirectQuery.

Define semantics once in Unity Catalog and publish them directly to Power BI semantic models

by Toussaint Webb, Joanna Zouhour, Chris Eubank and Jade Wang

Organizations want a single, trusted definition of their business semantics. Revenue, margin, and active customers should mean the same thing in every report, notebook, and AI application. When they don't, business users and AI agents read the same data differently and reach different answers. Finance and sales show different revenue numbers, teams lose trust in their reports, and decisions get made on the wrong numbers. Unity Catalog metric views, part of Unity Catalog semantics, solve this by enabling customers to define business KPIs once in Databricks, in an open, governed semantic layer that sits on top of the lakehouse.

At the same time, many of these organizations rely on Power BI as the front end for their business users. Often, organizations have thousands of PowerBI workspaces each with its own Semantic Models, creating a governance and unification nightmare. Furthermore, when each team builds its own metrics and relationships in Power BI, the same logic lives…
