It's About Data Ontologies, Semantics, AI and the Microsoft Data Ecosystem
Mar 14, 2026
Andrew Brust, founder of Blue Badge Insights and longtime Microsoft data platform expert. He explores how Microsoft Fabric and Fabric IQ connect AI to business data. He explains why ontologies and semantic layers matter for reducing hallucinations. He discusses graph engines, agents, and practical ontology adoption and who should build them.

Episode notes
Fabric IQ Bridges AI And Data Platforms
- Microsoft Fabric IQ links AI and Fabric by adding ontology and orchestration to make AI an intelligent consumer of business data.
- Andrew Brust explains Fabric IQ brings graph engines, ontologies, and agents to stitch lakes, real-time event houses, and BI models together.
Structure Is The Antidote To Hallucinations
- Grounding generative models with structured data and business vocabulary reduces hallucinations and improves relevance.
- Andrew Brust argues ontologies let models interpret domain terms of art, not just plain language, improving enterprise trust.
Dimensional Models Are Not Full Ontologies
- Power BI's dimensional semantic models are close to ontologies but limited to slicing numbers by dimensions.
- Brust notes dimensional models work for BI but aren't enough for full natural language queries across relationships.
