Day 2 & Day 3 of Data Analysis with Power BI

📊 Data Import, Cleaning, and Transformation:
Over the course of Day 2 and Day 3, our learners delved into various aspects of data analysis with Power BI. They began by mastering data import techniques and exploring the robust features of Power Query for data cleaning and transformation. This included resolving inconsistencies, managing null values, and applying user-friendly value replacements. Learners also learned how to profile columns, change data types, rename objects, and pivot data to ensure their datasets were ready for deep analytical tasks.

🔄 Building Semantic Models:
A key focus was on simplifying complex data models using star schemas to create efficient semantic models. Learners studied the terminology and implementation of star schemas, understanding the importance of correct data granularity for performance and usability. They also learned to create common date tables, configure one-to-many, and many-to-many relationships, and resolve circular relationships. By the end of these sessions, they were equipped to improve the performance of their Power BI models and make a simple visualization from sample data.
