Power BI Get Data: Choosing Import, DirectQuery, or Live Connections Explained

Описание: After watching this video, you'll confidently understand the differences between Import, DirectQuery, and Live connections in Power BI, enabling you to choose the best data connectivity mode for your reports.

Adam Saxton breaks down the three main ways to get data into Power BI Desktop: Import, DirectQuery, and Live connections. He explains how Import mode caches data inside Power BI for fast performance and full feature support, while DirectQuery queries data live from the source, useful for very large datasets but with some limitations. Live connections connect directly to Analysis Services or Power BI datasets without importing data, and Adam also covers composite models that combine these modes. Throughout, he provides practical examples and tips to help you optimize your Power BI data models and improve report performance.
