What types of relationships can be created between tables in Power BI?

In Power BI, relationships between tables are crucial for data modeling, allowing users to analyze data across different sources effectively. The correct answer indicates that Power BI supports three types of relationships: one-to-one, one-to-many, and many-to-many.

A one-to-one relationship occurs when a row in one table is related to one and only one row in another table. This type of relationship is less common but can be used effectively in scenarios where unique identifiers match exactly.

A one-to-many relationship is the most widely used type in Power BI. In this scenario, a single row in one table relates to multiple rows in another. For instance, a customer can have many orders, where each customer record corresponds to one or more orders in the orders table.

Many-to-many relationships allow for more complex data associations where multiple rows in one table correspond to multiple rows in another. This is particularly useful in scenarios involving many-to-many interactions, such as students enrolled in multiple courses, where each course may have multiple students.

By allowing these three types of relationships, Power BI provides flexibility and robustness needed for a variety of data scenarios, enabling effective data analysis and visualization. Understanding and utilizing these different relationship types is essential for building sophisticated data models that yield insights from interconnected datasets
