BigData / Tableau Interview Questions

Advantages of Tableau.

Visualize Data: Rather than having complex computations over an Excel sheet, Tableau provides beautiful insights, data blending, and dashboarding derived from the data.

Create interactive visualizations: Tableau provides a drag-n-drop facility to quickly let the users interact with the data. You can check some of the templates created using Tableau in the Tableau gallery.

With Tableau's gallery of templates, you can choose your option and customize it. With data visualization features, you can easily embed tons of information in the form of infographics that appeal to the audience.

Easy implementation: With drag-and-drop options, Tableau is reportedly easier to use. This is one such tool that you can learn without having any coding background or experience in Python, Business objects, or DOMO.

Handle large amounts of data: Tableau is competent enough to handle millions of rows without affecting the dashboard performance.

Integration with scripting languages: With Tableau, you can perform complex data computations using scripting languages like Python and R by importing some visuals or packages.
