Advanced Data Modeling Techniques for Power BI - Storage Modes, Composite Models, and Calculation Groups

Level up Power BI data modeling skills in this 51-minute conference talk from SQLBits. Learn to handle different source groups, storage modes, and composite models in Power BI. Discover how to avoid redundant measures by implementing calculation groups and tackle the challenges of combining them with remote and local Power BI models. Explore topics such as Dual mode, DirectQuery, security implications, and performance considerations. Gain insights from speakers Jeroen ter Heerdt and Marc Lelijveld as they cover AdventureWorks examples, composite models using Power BI datasets and Analysis Services, and key takeaways for expert-level data modeling in Power BI.
