This course develops the skills needed to transform raw business data into reliable, interactive Power BI reports and dashboards. Designed for participants transitioning from Microsoft Excel or Google Sheets, it covers the complete analytics workflow: defining business questions, connecting to data, preparing and transforming datasets, building data models, creating DAX calculations, designing visualizations, and publishing and maintaining reports.

Participants progress from core Power BI concepts to advanced dashboarding, including normalization and selective denormalization, star-schema modeling, time intelligence, interactive reporting, performance optimization, row-level security, and deployment governance. The course also introduces SQL for retrieving and preparing data and communicating findings that support business decisions.

Duration 4 Days – 28 hrs.
