This is the recording of the live session presented by Marco Russo at the Persian Power BI User Group.

The sentence "many-to-many relationships" has different meanings in Power BI.
The "classic" many-to-many relationships in a data warehouse is a design pattern requiring a bridge table.

A many-to-many cardinality relationship in Power BI is different from the one commonly used in dimensional modeling, and it commonly solves a granularity issue in managing data coming from different data sources.

This video clarifies design patterns and best practices for using the different types of many-to-many relationships in a Tabular model for Power BI and Analysis Services.

Hi Marco, I had to watch two of your presentations on the same topic to get it but I finally got it!! This has been a huge handicap for me. Lack of this knowledge has been truly a handicap for me. Because of that, I have been missing great opportunities to showcase phenomenal analysis. Thank you for everything and wish you a happy new year.
