In the previous chapter, we looked at some data modeling best practices, such as dealing with many-to-many relationships using bridge tables, dealing with inactive relationships, and how to programmatically enable them. We also learned how to use config tables, organize our data model, and reduce the model's size by disabling the Auto date/time feature in Power BI Desktop.
This chapter will discuss some advanced data modeling techniques that can help us deal with more complex scenarios more efficiently. Some techniques we'll discuss in this chapter only used to be available for the data models that were backed in a premium capacity. However, they are now available under the Power Pro licensing plan as well. In this chapter, we will cover the following topics:
- Using aggregations
- Incremental refresh
- Understanding parent-child hierarchies
- Implementing roleplaying dimensions
- Using calculation groups
