Qlik Sense Engine can be extended to use analytic connections, usually called Advanced Analytics Integration (AAI), that integrates external analysis. An analytic connection extends engine capacity, adding expressions that can be used in charts or scripts. When Qlik Sense needs to use these analytics connections, Qlik Sense Engine calls that external calculation engine, executing functions that are usually named Server Side Extensions (SSE). For example, you could create an analytic connection to R and use statistical expressions thorough a SSE when you load the data from your script.

In this section, we will discuss how Qlik technology implements those connections and extensions to connect to platforms like R and Python.
