Chapter 10. Basic Data Transformation

At this point in the book, we've already covered topics related to data sources such as extraction, data visualization, scripting, and data modeling. These topics are all interconnected in the development process. We will now complement these four topics with a fifth subject that is of fundamental importance, and one that plays an essential role when developing QlikView apps, taking to an advanced level the lessons learned from all of the previous chapters: Data Transformation.

The topics we'll cover here will help us:

  • Make the data sources adequate to meet our data model design requirements

  • Deal with unstructured tables (such as Crosstables) and incorporate them into our data model

On we go.
