Tableau was started in 2003, and it is a business intelligence tool. Tableau allowed you to view your business data visually! 

Simply Put – Tableau entirely focuses on Visual Analytics.

In a world where data flows like crazy, visualization can help make quick decisions based on data.

Tableau can support and connect to a wide variety of data sources like the cloud, DBMS, excel sheets and even can connect to real-time data from websites.

What is the Need for data visualization with Tableau?

That’s where data visualization helps! 

What Tableau does is that at the back end, it writes optimized sequel queries in order to fetch your data from the database and then present it to you in a visual form that is easy to understand, insightful, and attractive – helping understand data much better.
