What is Tableau?

Tableau is a user-friendly tool designed for complex data visualization and simplifying large volumes of data. It empowers users to create insightful visualizations and graphics without the need for programming knowledge.

The platform was built with the goal of delivering fast, responsive, and intuitive business software. Tableau helps businesses gain insights quickly and present data in a way that’s easy to understand for clients and stakeholders. It is scalable, efficient, and easy to deploy.

History of Tableau

Tableau Software was developed in the United States, in Seattle, Washington. It was created by Professor Pat Hanrahan and Ph.D. student Chris Stolte, who specialized in data visualization techniques. Their objective was to make exploring and analyzing relational databases and data cubes more intuitive.

They combined SQL (Structured Query Language) with graphics to invent a visual query language called VizQL (Visual Query Language). This led to the development of Polaris, an interface for exploring large datasets.

In 2003, Chris Stolte brought in his former partner Christian Chabot as CEO, and Tableau was officially launched.

Tableau is capable of converting data from relational databases, spreadsheets, cubes, and cloud services into interactive dashboards. The company’s revenue grew from $34.2 million in 2010 to $64 million in 2011.
