Focus on the most important and most often overlooked factor in a
successful Tableau project-data. Without a reliable data source,
you will not achieve the results you hope for in Tableau. This book
does more than teach the mechanics of data preparation. It teaches
you: how to look at data in a new way, to recognize the most common
issues that hinder analytics, and how to mitigate those factors one
by one. Tableau can change the course of business, but the old
adage of "garbage in, garbage out" is the hard truth that hides
behind every Tableau sales pitch. That amazing sales demo does not
work as well with bad data. The unfortunate reality is that almost
all data starts out in a less-than-perfect state. Data prep is
hard. Traditionally, we were forced into the world of the database
where complex ETL (Extract, Transform, Load) operations created by
the data team did all the heavy lifting for us. Fortunately, we
have moved past those days. With the introduction of the Tableau
Data Prep tool you can now handle most of the common Data Prep and
cleanup tasks on your own, at your desk, and without the help of
the data team. This essential book will guide you through: The
layout and important parts of the Tableau Data Prep tool Connecting
to data Data quality and consistency The shape of the data. Is the
data oriented in columns or rows? How to decide? Why does it
matter? What is the level of detail in the source data? Why is that
important? Combining source data to bring in more fields and rows
Saving the data flow and the results of our data prep work Common
cleanup and setup tasks in Tableau Desktop What You Will Learn

A World Vision CEO shares personal stories and anecdotes to inspire
and give hope. Some stories need to be shared beyond a moment and a
place, as they can be wonderful illustrations of the human
experience. In a world that is full of challenging and
soul-searching events, Tim Costello shares stories he has
encountered in often the most dramatic of circumstances. He
believes life has a way of giving us the power to persevere during
hard times, and in Hope he shows us how. Hope is a book to savor
and brings home the importance of love, life, and finding the best
that there is to be found in people. A book that reminds us all
that there are so many that suffer yet still we can find hope.
Costello proves that hope can be found in the smallest of moments.
