I walk through a new feature in Tableau 2025.1 that lets you view the data model directly inside a worksheet. Using the Bookshop demo dataset, I build a simple count-distinct analysis of libraries stocking a book, then show how the new view helps you diagnose how the data model drives your numbers.

## Key takeaways

- Tableau 2025.1 adds a 'View Data Model' option under the Worksheet menu, showing the model relationships behind a specific sheet for the first time
- The 'Hide unused tables' toggle strips the model down to only the tables driving the current view, making it easy to trace which relationships affect your numbers
- When numbers are disputed, you can view raw data and then inspect the data model to check that relationships like editions and catalogues are resolving correctly
- Tim favours relationships over joins and unions, arguing union work belongs upstream in a warehouse or in a better SQL query
