Summary
In this chapter, we’ve covered many of the components of the data retrieval process used to support the dataset for this project as described in Chapter 1, Planning Power BI Projects. This included constructing a data access layer and retrieval process for a dataset and using M queries used to define and load the dimension and fact tables of the dataset.
In the next chapter, we’ll leverage the M queries and design techniques described in this chapter to create import and DirectQuery data models.
