This book does not assume any specific database knowledge, but it definitely will help to have some basic familiarity with data itself. We'll cover the foundational principles first, and while it may be tempting to skip the first chapter, please don't! We'll lay a foundation of terminology and the paradigm that will be used throughout the remainder of the book.

You'll be able to follow along with many of the examples in the book using Tableau Desktop and Tableau Prep Builder (in Chapter 10, Introducing Tableau Prep). You may download and install the most recent versions from Tableau using the following links:

• Tableau Desktop: https://www.tableau.com/products/desktop/download
• Tableau Prep Builder: https://www.tableau.com/products/prep/download

Please speak to a Tableau representative for licensing information. In most cases, you may install a 14-day trial of each product if you do not currently have a license.

For most chapters, you'll find applicable data files (Excel and text files) and a set of Tableau Workbook files, (.twbx) , or Tableau Flow files, (.tfl) , which you may open in Tableau Desktop or Tableau Prep Builder, respectively. These will follow the convention ChapterNN_Starter and ChapterNN_Complete (where NN is the chapter number). The starter workbooks and flows are intended to allow you to work through the examples in the book on your own, though at times, they will include completed examples for reference. The complete workbooks are entirely finished and are intended to allow you to check your work or see the finished example.

A block of code is set as follows:

IF [Animal] = "DOG" 
THEN
    IF [Age] < 2 
    THEN "Puppy"
    ELSE "Dog"
    END
ELSE [Animal]
END
