An Overview of Semantic Modeling in Microsoft Fabric

Teo Lachev talks semantic modeling:

In retrospect, I’d say I owe 50% of my BI career to Analysis Services and its flavors: Multidimensional, Tabular, and later Power BI. This is why I closely follow how this technology evolves. Fast forwarding to Fabric, there are no dramatic changes. Unlike the other two Fabric Engines (Lakehouse and Warehouse), Power BI datasets haven’t embraced the delta lake file format to store its data yet. The most significant change is the introduction of a new Direct Lake data access mode alongside the existing Import and DirectQuery.

Read on for Teo’s thoughts. I think there’s a good chance that the Bad/Ugly points will be eliminated by the time Fabric goes GA, though we’ll have to wait and see if that’s the case.
