Merge Queries vs Relationship

I am learning more about Merge Queries capabilities and I am not understanding when to merge vs to keep two seperate tables and build a relationship. Any good explanation?

  • PBInonpro , In Power BI we prefer Star schema, so we will merge the tables to create that.

    In case there is information needed time and again to do row-level calculations by the second table, then we will merge to avoid cross-table operation
