Raw data is rarely ready for reporting, and a poorly designed data model can lead to slow reports and incorrect calculations. Mastering the fundamentals of data modeling is the key to turning messy tables into a cohesive, high-performance reporting system. In this course, you will transition from importing raw tables to building structured, professional semantic models in Power BI. You will gain a deep understanding of data relationships, learn how to implement standard schemas, and write your first calculated columns and measures. What you'll learn: - Understand the core principles of data modeling and the difference between facts and dimensions. - Design clean star schemas and manage relationship cardinalities and cross-filter directions. - Write foundational DAX formulas to create calculated columns and measures. - Configure model properties, hierarchies, and display folders for cleaner report building. - Apply performance optimization best practices to keep your semantic models fast and efficient. You will start with key concepts and foundational terms before moving step-by-step through schema design, relationship configuration, and basic DAX calculations, practicing your skills through written explanations and code examples. This course is designed for aspiring data analysts and beginners who want to build a solid foundation in Power BI without any prior modeling experience.
