Just started watching the power bi videos and I must say, it's a progressive journey for me. I attended the first and second day of initial class so I started watching the videos from Video 3. In video 3, I extensively learnt, tables and its types, Relationships, Cardinalities, Star Schema, Hiding , Understanding and editing properties, Adding columns and understanding hierarchy. I was able to use the shared file to practice as I watch and was able to create more charts to further understand hierarchy. I am looking forward to exploring other videos in Power BI. All thanks to Folarin for exploring the Montessori way of schooling, it helped with feeling like I was in class presently.
