It is not only a visualization tool. It is using visualization techniques to bring data to life and help people think with data.

Our vision is one of ours most important senses. Tableau makes tabular data visually understandable. The people would be able to understand the meaning of data rather than looking at a long list of numbers. Data visualisation drives the engagement of the user.

There are lots of abuses in the field of data visualisation, according to the book (How Charts lie).

One of the right ways to help people understand meaning of data is knowing and respecting the users and providing freedom. Enabling them to have incremental interactions. Most importantly, immediate feedback. In Tableau everything is direct, safe and simple. Tableau has apply Tufte's techniques and best practices in the product.

To pull, adit, add information to a database. 

How does SQL work?
Think of:
- Database as a warehouse.
- Data tables as filing cabinets.
- Data as files.

This warehouse or database stores data.
The warehouse database was built using coding languages like C++ or C or Java
