Qlik Sense

During the development of this book, Qlik released their next generation product, Qlik Sense. Qlik Sense is not, currently, a replacement product for QlikView, and Qlik has announced that they will have a two-product strategy and sell QlikView for guided BI applications and Qlik Sense for self-service BI applications. A new version, QlikView 12.0, is slated for release in the second half of 2015.

While Qlik Sense is a new product, it is built on the same heritage as QlikView. There is a new data engine, QIX, that stores the data in a format more columnar than that of QlikView. However, the inference engine is still the same (green, white, and gray). The script syntax is still the same; in fact, we can use QlikView scripts in Qlik Sense. The frontend is very different because it is based on a new web design, but the expression syntax is still the same.

Therefore, much of what is written in this book about QlikView will still apply to Qlik Sense. Anyone who masters QlikView will be well on their way to mastering Qlik Sense.
