The Qlik Sense Data manager provides a way to pull data into Qlik Sense through an intuitive user interface. It contains a way to connect to your data sources, select the data you are looking to analyze, pull the data in, and link it to other data you have pulled in. Using Qlik's Cognitive Engine, and AI created by Qlik, the Qlik Sense Data manager automatically profiles your data and recommends how to connect different tables based on similar data keys. We'll go further into this profiling capability and how to transform data in the Self-service with Qlik Sense section at the end of this chapter.
