Joshua should apply rules to the fact tables.

Here's why:

1. Fact tables in a data warehouse typically contain the quantitative information (like sales amount, quantity sold etc.) and foreign keys to dimension tables.

2. Row-level security (RLS) is about restricting data access at the row level. For example, a sales manager for a particular region should only see sales data for their region and not for others. This kind of restriction is typically based on the data in the fact tables.

3. Applying RLS to fact tables ensures that only the relevant rows (data) are fetched from the database, which can significantly improve the performance of Power BI reports.

4. While dimension tables contain descriptive information (like product name, customer name etc.), applying RLS to dimension tables might not be as effective because they don't usually contain the data that needs to be secured.

5. Hierarchies are a way of organizing data in dimension tables. Applying RLS to hierarchies might not be necessary or effective for the same reasons as dimension tables.

So, to enforce RLS and deliver the fastest possible performance in Power BI reports, Joshua should apply rules to fact tables.
