Summary

One of Power BI's strengths is that you don't need to flatten your data into a single table. Instead, you can use multiple tables from multiple sources and define the relationship between them.How to manage your data relationships

The Model view in Power BI Desktop allows you to visually set the relationship between tables or elements. A relationship is where two or more tables are linked together because they contain related data. This enables users to run queries for related data across multiple tables. Use the Model view to see a diagrammatic view of your data.
