Relationship In Tableau

Welcome to our new video on Relationship In Tableau.

Relationships are a dynamic, flexible way to combine data from multiple tables for analysis. A relationship describes how two tables relate to each other, based on common fields, but doesn’t merge the tables together. When a relationship is created between tables, the tables remain separate, maintaining their individual level of detail and domains.

Think of a relationship as a contract between two tables. When you’re building a viz with fields from these tables, Tableau brings in data from these tables using that contract to build a query with the appropriate joins.
