Microsoft Power BI is a comprehensive business intelligence suite that combines robust data connectivity, transformation capabilities, advanced modeling, and interactive visualization into an integrated platform. It operates on a multi-layered architecture with distinct components for data preparation (Power Query), modeling (Analysis Services tabular engine), visualization (canvas and report objects), and distribution (Power BI Service). The platform supports complex analytical scenarios through its DAX expression language, enables enterprise-grade governance, and provides both self-service and managed BI capabilities across desktop, web, and mobile interfaces.
