Tableau Desktop vs Tableau Server
|Tableau Desktop||Tableau Server|
|Tableau Desktop allows users to create dashboards, user-stories, worksheets, and more that connect to various data sources (files or servers).||Tableau Server enables users to publish the dashboards data, user-stories, worksheets, and more, which they create using Tableau Desktop.|
|Users can share their work locally by sending a workbook (with .twbx file extension) to recipients who already have Tableau Desktop installed on their system.||After users upload a workbook to the server, recipients only need the credentials of Tableau Server to can access the file, without installing Tableau Server.|
|With this local sharing, the recipients can make changes to the original workbook and, thus, there can be multiple versions of the same file.||Using Tableau Admin, users can assign permissions for individual recipients. If one has the editing permission, he/she can make changes to existing files/reports leveraging the online version of Tableau Desktop.|
|One great benefit of Tableau Desktop is its report creation feature that allows users to create reports that help their stakeholders make informed decisions.||Tableau Server is the best for decision-makers to analyze results without having to install the tool, thus saving time and effort.|
Having a Tableau certification in your portfolio will be a testimony of your Tableau skills that will make you get noticed by hiring managers directly.
