Introduction
What is a script in Qlik Sense? In layman's terms, a script instructs the Qlik Sense engine on how to extract the data from the data source and what to do with it.
It forms an essential component of the ETL process. Hence, it is important to have a well-structured script in order to load the data efficiently. A good understanding of how to optimize an ETL process leads to a better data model. A good data model is one of the core components alongside well-written expressions to realize a good user interface performance.
