Chapter 8: Data Modeling Components
In the previous chapter, we learned about some critical data preparation best practices such as loading a proportion of data, removing unnecessary columns, and summarization to optimize our data model size. We also learned about query folding and how it can affect our data modeling in Power BI. We also looked at data type conversion and discussed the importance of selecting certain data types, in order to keep our data model more optimized when we import the data into the data model. This brings us to this chapter. All our data preparation efforts pay off by having a cleaner data model that is easier to maintain and performs well. In this chapter, we'll look more closely at data modeling in Power BI by covering the following topics:
- Data modeling in Power BI Desktop
- Understanding tables
- Understanding fields
- Using relationships
In this chapter, we'll work on the Chapter 8, Data Modelling and Star Schema.pbix sample...
