Terms in this definition
- Measure
A figure like total revenue, worked out by aggregating fact table data wherever dimensions intersect within a semantic model.
- Microsoft Security Copilot
Security assistant powered by generative AI, used in its own portal or embedded in Intune, Entra, Defender and Purview, and extensible with agents and plugins.
- Capacity
A reserved block of compute for a tenant whose size is fixed by its SKU; Fabric F SKUs express it in capacity units (CUs). Workspaces assigned to it unlock features like Copilot, and from F64 upwards people with free licences can view Power BI content.
- Overage
Fabric capacity consumption, after smoothing, that exceeds what the SKU allows in a timepoint. Any overage left after the 10-minute throttling window carries forward and is paid off by later idle time; alternatively, capacity overage billing at triple the usual rate avoids throttling.
- Workspace
Teams in Power BI and Microsoft Fabric collaborate in this folder-style container, which groups items such as reports, semantic models and lakehouses, controls who can access them and is assigned a capacity.
