To get the most out of this book

Qlik Sense Cookbook requires you to have at least a basic understanding of Qlik Sense. You should have either already deployed a couple of Qlik Sense apps or have worked extensively with QlikView before if you are now looking to transition to Qlik Sense.

To make the most out of this book, you don't necessarily read it from the beginning until the end (although it's recommended), but you should feel encouraged to start a chapter you're interested in and follow all recipes until the end because some recipe depends on the previous ones. Cross-references between recipes are made to ensure you know where to continue your reading if you wish to deepen your knowledge.

To closely follow the practical examples and to make the most of the code snippets, please ensure you download the latest version of the Qlik Sense Desktop client from the official website, which can be found here https://www.qlik.com/us/try-or-buy/download-qlik-sense.

In the time of writing the book, several versions of Qlik Sense were launched introducing new features but also changes to the UI. At the time of writing of the book, we were using Qlik Sense version February/2018. We carefully wrote the recipes to work correctly with the most recent versions, but the recipe about geo map will not work with the current steps presented because the Map object was entirely updated in version April/2018 and June/2018.
