Consultants must establish reliable and efficient data integration strategies. Using Power Query transformations instead of DAX for preprocessing ensures optimized processing. On-premises and cloud data sources should be securely connected via Power BI Gateway. API integration should follow pagination techniques to handle large datasets efficiently. Dataflows should be utilized for reusable ETL processes, reducing redundancy. Ensuring data consistency through deduplication, proper data types, and cleansing is crucial. Well-structured refresh schedules and Power BI consultant help maintain accurate, reliable, and high-performance integrations across multiple platforms.
