Tableau Desktop creates a connection between the innumerable types of files and Data Warehouse for live data examination.
The workbooks and dashboards created in Tableau Desktop can be shared in public or local. Tableau Desktop is further classified into two parts namely Professional and Personal, depending on the data source and publishing option connectivity.
The workbook is made private and limited access is provided in Tableau Desktop Personal, whereas the workbooks are made public through online or within Tableau server in Tableau Desktop Professional. Professional is the best option if the user desire to publish their workbook in Tableau server.
Workbooks can be saved in the Tableau public but it is accessible to everyone in the public. Tableau Public is particularly constructed for profitable users. You cannot save the workbooks in your local system if created in Public. The workbook can be stored in Tableau’s public cloud that can be opened and read by anyone.

Data that comes out of Tableau Online or Tableau Server supports Salesforce.com and Google Analytics.
Though we cannot modify or change the data, we can view or filter the existing workbooks using Tableau reader. Using Tableau Reader, a free tool, you can view the workbooks and visualizations created through Tableau Public or Tableau Desktop. In this reader tool, you can filter data, but cannot edit or modify. Anyone can view the workbook and hence we cannot expect security in Tableau Reader. The receiver must have Tableau Reader to read or view the documents shared by the other user.

There are three types of components in Tableau Server which are VizQL Server, Application Server, and Data server. VizQL server is to change the queries into visualization from the data source. An application server is helpful in providing authentications and authorizations. The data server is a central data management system, which is useful in managing and storing data from external data sources. Metadata Management, Data Storage, Data Security, Driver requirements and Data Connection are the services provided by the Data Server component.
Directing the requests to Tableau components from users is the process handled through Gateway. The requests are forwarded to the external load balancer while receiving client requests. If there is no external load balancer, Gateway by itself works as a load balancer.
With the help of various clients, users can view and edit the dashboards and visualization in Tableau server. Tableau Desktop, Mobile applications, and web browsers are the different clients used over here.
