You can optimize a Power BI semantic model by analyzing its star schema design, refining DAX measures, adjusting relationship cross-filter directions, and improving cardinality to make the dataset faster to query and easier to maintain.

The best way to design a star schema in Power BI Desktop is to analyze and distinguish fact tables from dimension tables, then refine relationships, naming standards, and hidden fields to ensure a clean, maintainable model structure.

Implementing row-level security in a Power BI dataset involves connecting to the active model and inspecting existing security rules to create or refine the filters needed to safely restrict data access across your semantic model.

Yes, you can use Power BI Modeling tools to fix broken relationships by connecting to the active model, inspecting the relationship metadata, and applying concrete modeling improvements to resolve cross-filter and cardinality issues.

Yes, this approach works for documenting a Power BI dataset for handoff by inspecting the active model's tables, measures, and metadata to improve naming standards, descriptions, and hidden fields for clearer dataset communication.

You need to refine DAX measures and calculation groups in Power BI when analyzing semantic models for design issues, ensuring your measures are optimized, correctly structured, and perform efficiently within the Power BI Desktop or Fabric environment.
