What is Relationships and Cardinality?
Cardinality describes the relationship between the number of matching rows on each side of a relationship, such as one-to-many, many-to-many, or one-to-one. Power BI needs to know the cardinality to correctly propagate filters between tables. Most well-designed models rely on one-to-many relationships between a dimension and a fact table.
