How to Create Relationships in Tableau - A Smarter Way to Connect Data

🔗 Understanding Relationships in Tableau – Why They Matter for Better Data Models

Creating relationships in Tableau is a modern, flexible way to connect multiple data sources without the rigid structure of traditional joins. In this tutorial from Jay Binning at Sport Horizon UK, we walk through how relationships work, why they’re different to joins, and how they can simplify your data modelling process.

Relationships are Tableau’s default method for connecting tables in the data model. Unlike joins, they maintain the logical independence of your data sources, preserving row-level detail and reducing duplication or aggregation issues. This approach is particularly useful when working with sports performance data, where datasets can vary in granularity, for example, linking player profiles to training logs, or match stats to wellness reports.

Whether you're new to Tableau or looking to improve how you manage multi-table data, understanding relationships is essential for building scalable, accurate, and insightful dashboards.

🧠 Perfect for sport scientists, performance analysts, and data professionals working with complex or layered datasets in Tableau.
