Consultants use best practices like reducing table size by removing unnecessary columns and data. They establish relationships carefully, choosing the correct cardinality and direction for optimal performance. Measures are preferred over calculated columns, and summarization tables are created for commonly used metrics. Aggregations are implemented to reduce query loads, and Power BI consulting services enable query folding to push transformations to the data source. These techniques ensure data models are efficient, scalable, and aligned with reporting needs.
