How does Tableau work?

The major work of Tableau software is to connect and extract the data stored in various places. It can pull data from any platform. Tableau can extract data from any database, be it Excel, PDF, Oracle, or even Amazon Web Services.

Once Tableau is launched, ready data connectors are available which allow you to connect to any database.

The data extracted can be connected live to the Tableau data engine, Tableau Desktop. This is where a Data Analyst or a Data Engineer work with the data that was pulled up and develop visualization. The created dashboards are shared with users in the form of static files. The users receiving dashboards view the files using Tableau Reader.

The data extracted from Tableau Desktop can be published to Tableau Server, which is an enterprise platform where collaboration, distribution, governance, security model, and automation features are supported. Using Tableau Server, end users can access the files from all locations, be it a desktop or a mobile phone. Want to become master in Tableau check out this Tableau Training in Sydney.
