What is Tableau?
Did you hear about Tableau and data science? How do these two relate? Well, Tableau is a powerful and fastest expanding data virtualization tool that is used in the Business Intelligence Industry. To make it more simple, Tableau is used to aid in simplifying raw data into one of the easiest ways it can be understood.
You are more likely to be told that data analysis is always very fast with the use of Tableau, and the visualizations are always created in the form of dashboards and worksheets. Any data that is always created and presented using Tableau can always be understood by professionals at any given level of an organization. It can also even be used by non-technical users to build a customized dashboard.

Tableau Product Suite
Have you ever operated Tableau before? If so, what does that suite contain? Well, if not, the tableau suite contains:
· Tableau Desktop
· Tableau Public
· Tableau Online
· Tableau Server
· Tableau Reader
You should also know that for you to easily understand the tableau tool, the data analytics is classified into two sections:
1. Developer Tools
2. Sharing Tools
1. Developer Tools
Here, the tableau tools that are readily available for development include the creation of dashboards, charts, report generation; virtualization also belongs to this category. Again, the tableau products that are found in this category are the Tableau Desktop and the Tableau Public.
2. Sharing Tools
Just as you can read the name, this tool is used in sharing the virtualizations, reports, dashboards that were previously created using the developer tools. What are some of the products that fall into this category? Well, some of them are Tableau Online, Server, and even Reader.
I think we should have a look at these products one by one.

You will absolutely fall in love with the rich features that allow you to code and even customize reports on the Tableau Desktop. Beginning from the creation of charts, reports, and even blending them together to form a dashboard are some of the great and necessary work that is created in the Tableau Desktop.
Do you know that for live data analysis, Tableau Desktop offers connectivity to the Data Warehouse and even other types of files? All the workbooks that are created here can either be shared locally or even publicly.
Based on the connectivity to the data sources and even publishing feature, Tableau Desktop is also classified into two:
· Tableau Desktop Personal: Here, the development features are the same as that of the Tableau Desktop. The personal version only ensures that the workbook is kept in private and that access to it is also limited. Again, here you cannot publish a workbook online; hence it can only be shared offline or in Tableau public.
· Table Desktop Professional: It is also much the same as the Tableau Desktop. The slight difference is that the work that is created in the Tableau Desktop can be published online or even on the Tableau server. Again, in the Professional version, there is full access to all sorts of data types. Are you looking to publish your work online? If so, then you need to choose this one.
This Tableau version is majorly built to accommodate cost-effective users. By simply using the word “Public” means that the workbooks that are created are not saved locally and that they should be saved in Tableau’s public cloud that is accessible by anyone.
You should also understand that there isn’t any privacy since the files that are saved to the cloud can be accessed and downloaded by anyone who is interested. Well, does this Tableau version perfectly fit? If you are an individual who is learning how to use Tableau, you can opt for this version as well as anyone who wants to share his or her data with the general public.
Do you know what a Tableau server is? Well, the software is usually used to share all the workbooks and even visualizations that are created in the Tableau Desktop application across an organization. For you to be able to share your dashboards in the tableau server, you must have already published your work in the Tableau Desktop. Again, once your work has been uploaded into the server, it will be accessible only to those users that are licensed.
Another thing that you need to know is that it’s always not necessary for the licensed users to have the Tableau server installed into their computers. All that these users need is the login credentials so that they can check the reports through their web browser. The security is always so high in the Tableau server, and at the same time, it’s much suited to fast and effective sharing of data in an organization.
The admin of an organization usually has full control over the server. The organization bears the maintenance cost of the hardware and the software.
Just as the name goes, Tableau online is an online sharing tool that is found in Tableau. Its functionalities are almost the same as those of the Tableau server, but the difference is only that the data is stored on servers that are hosted in the cloud and are maintained by the Tableau group.
Again, do you know that there are no storage limits on data that can be published in Tableau Online? Table online builds a direct link that is used to access more than 40 data sources that are not limited to MySQL, Amazon Aurora, Spark SQL, and several others.
For you to publish both the Tableau Online and the Server, you need to ensure that the workbooks are created by the Tableau Desktop. Other data that is streamed from the web applications such as Google Analytics, Salesforce.co are also supported by the Tableau Server and Tableau Online.
Have you ever heard about Tableau Reader before? Well, Tableau Reader is a free tool that enables you to view the workbooks and visualizations that are created with the help of the Tableau Desktop or even Tableau Public. You should also know that data available here can be filtered, but one cannot edit or modify anything. What about the security in the Tableau Reader? You should know that the security level in the Tableau Reader is at zero since anyone who has the workbook can view it using the Tableau Reader. Do you want to share the workbook that you have created? If so, the receiver should make sure that he or she has the Tableau Reader to view the document.
How does Tableau work?
Tableau will always connect and even extract data that is stored in different places. This tool can extract data from any platform imaginable. All types of data ranging from simple to more complex can be extracted using this tool. For instance, simple data such as an Excel, pdf and even more complex data such as Oracle, a database that is present in the cloud such as Amazon web services, Microsoft Azure SQL database, Google Cloud SQL, and even other data sources that are not mentioned here can be extracted using the table.
When Tableau is launched, ready data connectors are present, which allows you to access any of your preferred databases. Based on the kind of Tableau that you have purchased, the number of data connectors that are supported by the Tableau will always vary.

The extracted data can always be either connected live or even extracted to Tableau’s data engine, Tableau Desktop. Here is where the data analyst, data engineer work with the data that is extracted to create visualizations. The created dashboards are then shared with the users in the form of a static file. The users who receive the dashboard view the file with the help of the Tableau Reader.
Any data that is from the Tableau Desktop can be published to the Tableau server. You should also know that this is an enterprise platform that provides collaboration, distribution, governance, security model, and even automation features are supported. With the help of the Tableau server, the end users have the freedom of accessing all the files from all locations such as desktop, mobile, or even email.
Excel Vs. Tableau
Do you know that both Excel and Tableau are tools that are used to analyze data though they have some unique, different approaches when it comes to data exploration? You will notice that the analysis that is found in Tableau cannot be compared to that which is found in Excel.
Excel does work with rows and columns in spreadsheets, while Tableau allows the exploration of data using the drag and drop feature. Again, Tableau formats the data in the form of graphs, pictures that many people find to be so easy to understand.
If you decide to compare these two options, Tableau and Excel, you will notice that Tableau outdoes Excel in major areas such as interactive dashboards, virtualizations, capabilities to work with massive sets of data, and many other more areas.
