Power BI Masterclass - Learning DAX: Model Structure Challenge Applying Bridge Tables

The video tutorial explores a model setup challenge in Power BI, focusing on importing data from Excel and understanding table relationships. It highlights the importance of bridge tables in connecting trainers to trainings and discusses the limitations of bidirectional filtering. The tutorial provides three DAX-based solutions to address relationship issues, emphasizing the use of cross-filtering, context transition, and direct bridge table filtering. The video concludes with recommendations for avoiding bidirectional relationships to prevent ambiguity and performance issues.
