QlikView always desires a star schema as it is simple to understand and efficient for reporting. In this chapter, we learned different techniques of creating a star schema and converted our previously created data model into a star schema by using mapping loads, joins, and concatenation.
In the next chapter, we will learn about data modeling challenges, which are resolved by using cross tables, link tables, and the master calendar. You will also learn about handling slowly changing dimensions using the
Interval Match function. Finally we will use QVDs to read and write our data model tables.
