Qlik has its own script.
Basic understanding of SQL will help, basic understanding of one or more programming languages will help, but at the end of the day you will need to learn a new script (that has a lot in common with many other languages).
Qlik offers a QlikView Developer training for QlikView and a Qlik Sense Data Modeling training for Qlik Sense. The content of those trainings is about 95% the same.
We offer both classroom as online self-training. For more information go to:
As many already assisted:
- Knowledge of SQL will be good when writing the Qlik's script to load the data into your application.
- You will need to learn about SET analysis, AGGREGATE functions, which are very peculiar to Qlik.
- Any book about Qlik View or Qlik Sense will be good, as both products are pretty close relatives, obviously you will be better off with a book on Qlik Sense.
