They leverage Power Query for transformations and utilize native connectors to ensure seamless data imports. When working with non-Microsoft systems, consultants might employ third-party tools or APIs to bridge gaps. Power BI consulting services also create unified data models that optimize relationships across sources. Performance tuning, such as data compression and query optimization, is integral.
