Tableau is one of the best and powerful visualization tools these days. It is widely used in the field of Business Intelligence but it is also utilized in other sectors as well such as research, statistics, various industries etc.
It simplifies raw data into understandable format. We can also manipulate data in it to get desired results. It is very easy to use and doesn't require any technical background to work with. The visualizations are created in the form of Dashboards and Stories.
Tableau can be majorly classified into two sections:
Developers tool: This consists of the tools that allows us to do the actual work i.e. create dashboards, reports, charts, stories and other visualizations. The products under this category are Tableau Desktop and Tableau Public.
Sharing tools: The name is self-explanatory; it helps in sharing the visualizations created using developers’ tools. The products under this category are Tableau Online, Tableau Server, and Tableau Reader.
All in all, there are Five products in Tableau: Tableau Desktop, Tableau Public, Tableau Online, Tableau Server, and Tableau Reader.
As mentioned earlier, this is where all the major work is done. It has a lot of features that lets you create visualizations very easily. It provides connectivity to Data Warehouse and other file types such as excel, text, json, PDF etc. The visualization can be stored locally or publicly.
Tableau Desktop can be further classified in two parts:
Tableau Desktop private: where the workbooks are kept private, and the access is limited. The workbooks cannot be published online, it can only be distributed either Offline or in Tableau Public.
Tableau Desktop Professional: Here the only major difference is that the workbooks can be published online and there is full access to all the features.
It is the same as Tableau Desktop, but it is a public version i.e., it is free but the workbooks created cannot be saved locally. they can only be uploaded to Tableau's Public cloud where it can be seen and accessed by everyone. There is no privacy offered in this version. It is best for an individual who wants to learn working with Tableau.
It is essentially used to share the workbooks across the organization. The work needs to be published in Tableau Desktop first to be able to upload it on the server. Once uploaded, anyone with a license can view the work. Though it isn't necessary for the licensed user to have Tableau Server installed. If a person has valid login credentials, then he/she can view the work on a web browser. The admin of the organization will always have full control over the server.
It is an online sharing tool of Tableau. Its functionalities are similar to Tableau Server, but the data is stored on servers hosted in the cloud which are maintained by the Tableau group. There is no storage limit on the data that can be published.
It creates a direct link to over 40 data sources that are hosted in the cloud such as the MySQL, Hive, Amazon Aurora, Spark SQL and many more.
To publish, both Tableau Online and Server require the workbooks created by Tableau Desktop. Data that is streamed from the web applications say Google Analytics, Salesforce.com are also supported by Tableau Server and Tableau Online.
It is tool used to view workbooks created using Tableau Developer tools. It doesn't allow editing and modification in the workbook. Anyone having the workbook can view it using Tableau reader. In fact, if you want to share the dashboards created by you then the receiver needs Tableau Reader to be installed.
Tableau has the ability to connect to any platform to extract data. Simple databases such as excel, PDF; and complex databases like Oracle, a database in the cloud such as Amazon web services, Microsoft Azure SQL database, Google Cloud SQL and various other data sources can be extracted by Tableau.
