Chapter 4: Getting Data from Various Sources

In the previous chapters, we discussed some aspects of data modeling, including various layers in Power BI, how the data flows between different layers, virtual tables in Data Analysis Expressions (DAX), and how they relate to data modeling. We also discussed how to leverage the power of query parameters and create custom functions in the Query Editor with the Power Query formula language.

In this chapter, we will learn how to get data from various data sources. We then walk through some known challenges and common pitfalls in getting data from some of those data sources. We will also discuss data source certification and different modes of connection to various data sources.

In this chapter, you will learn about the following topics:

• Getting data from common data sources
• Understanding data source certification
• Working with connection modes
• Working with storage modes
• Understanding dataset storage modes
