Summary
In this chapter, we’ve covered a number of important concepts, design principles, data source settings, and source system preparation. This includes query folding, query design considerations per dataset mode, important Power BI Desktop configuration settings, data source privacy levels, and the layer of SQL views within a database source.
Understanding these concepts and properly preparing source systems greatly aids the process of connecting to and transforming data using Power BI.
In the next chapter, we’ll leverage the prepared source systems and design techniques described in this chapter to connect to source systems and transform their data using Power Query (M).
