Power BI Data Modeling for Beginners: Hierarchies and DAX

Raw data is only valuable when it is structured for analysis. If you are new to Power BI, learning how to connect tables, build hierarchies, and write calculations is the key to unlocking deep business insights. This text-based course guides you through the foundational steps of data modeling, helping you transition from working with flat files to designing efficient, structured models that power clear reports. What you'll learn: - Understand the core principles of data modeling, table relationships, and schema design. - Create custom hierarchies to enable seamless drill-down analysis in your reports. - Write your first DAX measures to calculate dynamic business metrics. - Apply DAX variables to keep your formulas clean, readable, and highly performant. - Configure matrix layouts to present multi-level data in a structured format. - Implement industry best practices for choosing between calculated columns and measures. You will start with essential terminology and the basic concepts of table relationships. From there, you will progress to defining hierarchies and writing functional DAX expressions through clear, step-by-step written explanations and practical code examples. This course is designed for beginners who are new to Power BI and data modeling, with no prior experience in database design or DAX required.
