Power BI Essentials: Data Transformation & Modeling with DAX

О курсе

This course equips business professionals, Power BI developers, and aspiring data strategists with the essential skills to transform raw data into actionable business intelligence using Power BI. You’ll begin by exploring the principles of data-driven decision-making — understanding how modern organizations harness analytics to inform strategy, optimize operations, and drive innovation. Through real-world examples, you’ll examine how Business Intelligence (BI) has evolved into a critical enabler of organizational agility and competitive advantage. Building on this foundation, the course introduces you to the Power BI ecosystem from its architecture and workflow to its integration within the Microsoft data landscape. You’ll learn to differentiate between traditional and modern BI tools, navigate Power BI Desktop and Service environments, and compare various versions and deployment models. Practical sessions guide you through installation, interface exploration, and connecting Power BI to diverse data sources. As you progress, you’ll master the end-to-end process of data preparation, transformation, and modeling. Using Power Query Editor, you’ll learn to clean, shape, and profile datasets for accuracy and quality. You’ll then design robust semantic data models by applying schema principles, managing relationships, and optimizing model performance for speed and scalability. These hands-on skills build the foundation for intelligent data storytelling and dashboard creation in later stages of your Power BI journey. The course culminates in a comprehensive introduction to Data Analysis Expressions (DAX), the powerful formula language that drives analytics in Power BI. You’ll develop fluency in writing DAX functions, creating calculated columns and measures, and understanding evaluation contexts. Advanced lessons introduce you to performance optimization and best practices for crafting efficient DAX expressions, preparing you to analyze data dynamically and with precision. By the end of this course, you will be able to: - Explain the strategic importance of BI in enterprise data ecosystems. - Differentiate between Power BI Desktop, Service, and other BI platforms for appropriate architectural design. - Apply data transformation and integration techniques using Power Query Editor. - Design and optimize relational and semantic data models using schema design principles. - Develop efficient DAX formulas, calculated columns, and measures to enable advanced analytics. - Evaluate model performance and implement best practices for scalable Power BI solutions. This course is ideal for Power BI developers, BI architects, data engineers, and analytics professionals who aim to master the technical and architectural aspects of Power BI implementation. It bridges analytical design with engineering precision, preparing learners to architect data solutions that are reliable, scalable, and insight-driven. Join us to master the foundations of Power BI, where data meets intelligence to empower better, faster, and smarter business decisions.
