Thank you very much for purchasing Mastering Qlik Sense! Both the authors are very excited to accompany you on your journey to becoming proficient and a master of Qlik Sense. Two new concepts are being introduced with the latest technology that make it different than QlikView: its improved self-service capabilities with the goal of democratizing data and data literacy within organizations, and the introduction of robust APIs that let you extend Qlik Sense using web technologies and take its analytics even further.

As such, due to the breadth of different new skill sets now required in a typical Qlik Sense project (web development, Qlik scripting, expressions, and business understanding for data analytics), it's nearly impossible to master them all. However, this book will provide you with synthesized and advanced knowledge of all relevant concepts around mastering Qlik Sense on an enterprise level.

As such, the book is specifically targeted at three groups of people:

• QlikView gurus: People who have extensively used QlikView in the past and are looking to transition to Qlik Sense
• Qlik Sense beginners: People who are new to Qlik but have had some experience using Qlik Sense in their organization and wish to bring their expertise to the next level and
• Web developers: Frontend and backend JavaScript developers who want to get a better understanding of the Qlik technology to leverage its rich and powerful API

Accordingly, the book is structured into three modules.

• Module 1, The Qlik Sense Self-Service Model: Module 1 is about understanding the essence of self-service and how Qlik Sense is facilitating this capability. This module will revolve around the various use cases in self-service, how to set up the security for this, and how to prepare an environment where non-technical users can be empowered to create their dashboards and visualizations. Emphasis will be put in this module on QlikView developers who are looking to understanding Qlik’s new product and to what extent they are different and similar.
• Module 2, Best Practices for Data Modeling and Expressions: Albeit very similar to QlikView’s best practices, it is essential that the audience knows and understands Qlik’s best practices on how to correctly and efficiently use the in-memory calculation engine to master the Qlik Sense technology.
• Module 3, Qlik Sense API: Qlik has decided to open up the Qlik engine as well as all of their services via an API. This suggests that extensions and integrations into third-party platforms are possible, which exceeds the capabilities that come out of the box in Qlik Sense. The real power of the associative engine can be leveraged in any way desired, which will be the topic of this module.

We hope you enjoy it!
