Hi friends
This is Sharat
welcome to ohio computer academy
I am a Tableau developer and a Trainer
Through this channel, i will help you guys in getting started in tableau.
what is tableau?
Tableau is a business intelligence application.
It helps in creating visualization, using graphs tables and maps.
you can connect to any kind of data,
helps business and understanding the
data and making informed decisions.
Tableau answers business questions using interactive dashboards.
Before starting in tableau let us understand
what is business intelligence concept?
BI is a concept that deals with analysis of
diverse data, BI uses different tools and
technologies to help in gathering, transforming and presenting data
presentation of data is such that it
helps business users in understanding
the data and arrive at meaningful
decisions.
By this you guys have understood about the business Intelligence concept I think.
Now we will see, how tableau works?
This is a front page that you will be seeing when you open
for the first time the tableau desktop tool and
when you install it on your machine,
this is the page that will show up.
Tableau can connect to any data source this data connection can be a
live connection or an Extract, it can also be a saved connection or
a published connection.
Tableau desktop is used to create workbooks.
these workbooks use data connections to create charts and tables.
users view this dashboard using tableau reader or a server.
As you are seeing on the screen,
you can find different types of connection options
like you can connect to excel file, text
file, access, json file or a statistical file.
Even you can connect to a different servers
that may be a tableau server, Microsoft sequel server, my sequel, Oracle
and the other different servers.
Here you can see on the screen, so if
whatever the server you are having you
can connect to that and you can connect
your own data.
Now we will be connecting to an excel file and
we will see how the data connection happens.
Let me connect to excel and I will go to my tableau repository.
This is a sample superstore file
that comes default one with the tableau installation on your machine.
now I'm connecting to the sample superstore file
and we will see the connection.
If you are a non technical guy nothing to worry.
Tableau use a drag-and-drop tool interface
so, if you have anything you can easily work on it.
Now what are the sheets you are seeing
those are the tables relating to the excel file.
so you can drag them onto the drag sheets here location and
you can see the data information down and on the top right side,
you can see the two types of connections that tableau can make.
It may be a live connection or an extract.
so now we have done the live connection.
After connecting to a data
just go to
the sheet 1 this is the developer location
that he will be done creating the charts or the graphs or the maps
relating to the work.
so i will create a basic chart by using a category and the measured field and
we will see what is the sales for each category and
I am going to create a bar chart relating to it.
Now, If you observe you can see a chart,
bar chart for each category
what is the sales it is doing,
by representing with different color codes and
this is an interactive worksheet and it will be a dynamic one
so this is the way that you will be creating the other all worksheet
once you create anything in the workbook level,
you will be publishing them on the server and
users will be interacting with them by using
a tableau reader or the server URL.
I hope this video helps in getting
an overview about the tableau.
we provide tableau training and
we cover these below topics in our tableau training,
those are understanding the basics, how to connect to the data?
transformation, calculations involving the tableau or other things
so these are all the concepts will be covering and
