Understanding relationships in Power BI
Relationships are the foundation of any Power BI or Analysis Services Tabular data model with multiple entities.

However, the ability to create multiple relationships between the same tables and the existence of bidirectional filters increase the complexity of this topic. In this session, Alberto Ferrari explains the complexity behind relationships and how they work in complex and potentially ambiguous data models.
