Power BI Semantic Layer Explained

The Power BI semantic layer is the model between raw data and the reports people open. This video explains what that layer is, what it is for, and how it keeps measures and relationships consistent. It covers datasets, relationships, and measures at a conceptual level, not a click-by-click build. Use it to see why analysts share one model instead of rewriting logic in every visual.
