10. • Tableau Server: Tableau server is essentially an online
hosting platform to hold all your tableau workbooks, data
sources and more. All you really need to know is that it works like
any other server, you can store things here and they will safe
from fires and pesky hackers. Tableau server is a product from
Tableau, it means you can use the functionality of Tableau,
without needing to always be downloading and opening
workbooks to open with Tableau desktop.
Not part of our course!

11. Why Tableau Server
• COLLABORATION! After all, isn’t the feedback and
collaborative working environment that Tableau promotes
a reason we all got into using Tableau in the first place? But
just how does server allow us to collaborate more
effectively? What I mentioned briefly earlier was the
functionality of using Tableau in the browser window.
• This means no links to dashboards that management staff
need to download and open, no slowing down of
computers whilst you wait for Tableau desktop to open,
and an easy way to comment on or even edit dashboards
online
