To get the most out of this book

This book does not assume specific database knowledge, but it will definitely 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 explore 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 15, Taming Data with Tableau Prep).

Most examples can be completed with almost any recent version of Tableau, but to fully explore the new Data Model capabilities, you will need Tableau 2020.2 or later.

You may download and install the most recent versions from Tableau using these 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 specific licensing information. In most cases, you may install a 14-day trial of each product if you do not currently have a license.

Depending on the terms of your license, Tableau also typically allows you to use your license on two machines. This means you might have Tableau installed at the office (perhaps even an older version) but can also install the latest version on your home machine. Check your licensing agreement and speak to a Tableau representative to verify details in your case.
