Tableau is a tool for generating data visualizations. By presenting information in the form of graphs or diagrams, it becomes easier to understand for all corporate teams.
Without the need for IT expertise, everyone can benefit from the advantages of data. Even non-technical users can create customized dashboards.
Data analysis is a breeze with this tool. Visualizations can then be created in the form of dashboards. Tableau’s main functionalities are real-time analysis, data visualization, and collaboration.
Thanks to its accessible and versatile nature, Tableau has won over many companies in all sectors. Today, it is a very popular Business Intelligence software.
Tableau tools fall into two categories: developer tools and sharing tools. The first category is used to develop dashboards, charts, reports, and visualizations. These are Tableau Desktop and Tableau Public.
First of all, Tableau Desktop allow you to code and customize reports. Graphs and reports can be created and combined to form a dashboard. You can also connect Tableau Desktop to a data warehouse for real-time data analysis.
Tableau Desktop software is available in “personal” and “professional” versions. The personal version limits access, and does not allow workbooks to be shared online. The professional version allows workbooks to be published online or on Tableau Server.
The Tableau Public version is more economical. It does not allow workbooks to be saved locally, but only on the public cloud.
Tableau Server software is dedicated to sharing workbooks and visualizations. Once uploaded to the server, the dashboard created with Tableau Desktop is accessible to other users.
The Tableau Online platform enables online sharing. Its functionalities are similar to those of Tableau Server, but data is stored on servers hosted in the Cloud and maintained by the publisher. This platform connects to over 40 data sources, including MySQL, Amazon Aurora, and Spark SQL. Last but not least, the free Tableau Reader tool lets you view visualizations created with Tableau Desktop or Public.
Tableau connects to various sources to extract data. These can be databases, Excel files, PDFs, and much more. Native connectors are ready to use.
