Tableau Server Components

 

The work of Tableau Server is handled with the following four server processes:  

 

Application Server:    Application Server processes handle browsing and permissions for the Tableau Server web and mobile interfaces.   

 

VIZQL Server:   Once a view is opened, the client sends a request to the ViZQL  process.The ViZQL process then sends queries directly to the data source, returning a result set that is rendered as images and presented to the user. Each ViZQL Server has its own cache that can be shared across multiple users.

 

Data Server:  The Tableau Data Server lets you centrally manage and store Tableau data sources. It also maintains metadata from Tableau Desktop, such as calculations, definitions, and groups. The published data source can be based on:  • A Tableau Data Engine extract  • A live connection to a relational database (cubes are not supported)   

 

Backgrounder:   The backgrounder refreshes scheduled extracts and manages other background tasks.

 

Data Connectors:  Tableau includes a number of optimized data connectors for databases such as Microsoft Excel, SQL Server, Oracle, Teradata ,Vertica , Cloudera Hadoop  and many more. 

There is also a generic ODBC connector for any systems without a native connector.   

 

Tableau provides two modes for interacting with data:  

 • Live connection  

• In-memory.  

 Users can switch between a live and in-memory connection as they choose.

 

Clients: Web Browsers and Mobile Apps

 

Tableau Server provides interactive dashboards to users via zero-footprint HTML and JavaScript (AJAX) in a web browser, or natively via a mobile app. No plug-ins or helper applications are required. Tableau Server supports:  

 

Web browsers: Internet Explorer, Firefox, Chrome and Safari
