Post No. #772 Native Queries in Power BI : In Power BI, a native query refers to a SQL query that you write directly when connecting to a database. This allows you to control exactly what data is being fetched from the source and can be more efficient because you can filter and manipulate data at the source rather than bringing it all into Power BI and then filtering it.

Post No. #769 Row-Level Security (RLS) in Power BI is a feature that controls access to data at the row level for individual users or groups. - It restricts data visibility by applying filters within roles, ensuring that users only see the data they are authorized to view based on the criteria specified in these roles. - RLS is used to enforce data privacy and security by limiting data access dynamically, often using DAX expressions that tailor data views according to the user's identity.

Post No. #768 In Power BI, cross-filter direction determines how filters are applied across related tables in your data model: Single Direction: Filters flow in one direction, typically from the "one" side of a relationship to the "many" side. Useful for straightforward, hierarchical models. Both Direction (Bi-Directional): Filters flow in both directions between related tables. Useful for complex models where tables need to filter each other, such as many-to-many relationships.
