What is Tableau? Tableau is a visual analytics platform transforming the way we use data to solve problems—empowering people and organizations to make the most of their data.Tableau is an excellent data visualization and business intelligence tool used for reporting and analyzing vast volumes of data. It is an American company that started in 2003—in June 2019, Salesforce acquired Tableau.

The most commonly used file type in Tableau that has information about worksheets, dashboards, and stories.
Tableau Packaged Workbook(.twbx)
A packaged zip file that enables users to share their work with those who don't have access to the original data.

These files are shortcuts for quickly connecting to the original data that you use often. It does not contain the actual data, but has the information needed to connect to the real data and any modifications you've made to the data.
Tableau Packaged Data Source(.tdsx)
A zip file that has the data source file and any local file data, such as extract files (.hyper or .tde), text files, Excel files, Access files, and local cube files.
Tableau Data Extract(.tde or .hyper)
This contains a local copy of a subset or entire dataset that can be used to share data with others when you have to work offline and improve performance.

This enables you to save worksheets and share them with others so that they don’t have to create a new worksheet from scratch and can use it in their workbooks.

Dimensions and Measures in Tableau Once you load a dataset, Tableau automatically divides the data into dimensions and measures. You can see this in the workspace area under the data pane.
Dimensions are usually categorical fields that cannot be aggregated, while measures are numerical fields that can be measured, aggregated, or manipulated.
Dimensions are marked in blue, while measures are marked in green.
