Power BI is the world's most widely adopted enterprise BI platform — combining data preparation (Power Query), data modeling (semantic models with DAX), visualization (interactive reports), and distribution (Power BI Service, embedded, mobile). Power BI integrates natively with the Microsoft ecosystem: Excel, SharePoint, Teams, Dynamics 365, and Microsoft Fabric.
Enterprise Power BI requires more than report building: semantic model architecture (star schema design, DAX calculation groups, composite models), governance (deployment pipelines, workspace management, row-level security), and performance optimization (aggregations, DirectQuery tuning, incremental refresh).
