Data analysis becomes fast with Tableau, and visualizations are created in the form of dashboards and worksheets. A non-technical user can also create a customized dashboard.

The main features of Tableau are:

• Data Blending
• Real-time analysis
• Collaboration of data

Organizations such as Amazon, Accenture, and Walmart also use Tableau.

Given below is a template of the Tableau Dashboard:

Tableau is used because it can analyze the data quickly. With the help of Tableau, you can create dashboards that contain actionable insights and drive the business forward.

How does Tableau work?

The main objective of Tableau software is to connect and extract the data that is stored in various places. Tableau can pull data from any platform. It can pull data from any simple database such as pdf, excel to a complex database such as Oracle, Google Cloud SQL, etc.

As soon as Tableau is launched, the ready data connectors that are available allow you to connect to the database. The number of data connectors supported depends on the version of Tableau.

The data that is pulled can either be connected live or extracted to the Tableau’s data engine, Tableau Desktop. The Data Analyst, the data engineer, takes data from here and develops visualizations. The created dashboard is then shared with the users through a static file. The users view this file using Tableau Reader.

The data is then published to the Tableau Server. Tableau Server is an enterprise platform where features such as collaboration, distribution, governance, security model, automation features are supported. The end-user can access the files from any location using Tableau Server. It can be either a desktop, email, or mobile phone.

There are two ways in which Data Analytics of Tableau can be described:

1. Developer Tools: Tools that are used in the development, such as charts, dashboards. Ex. Tableau Public and Tableau Desktop.
2. Sharing Tools: Tools used for sharing reports, visualizations. Ex. Tableau Reader, Tableau Server, and Tableau Online.

Advantages of Tableau:

• Fantastic Visualizations: You can create a range of visualizations. You can also switch between different visualizations.
• In-depth Insights: You can look at the same data from different angles. You can also dynamically add components for comparison and analysis.
• User-Friendly approach: People not having any technical skills or coding knowledge can also use Tableau. This means that no prior skill set is required. It is self-depicting as most of the features are in drag and drop format.
• Working with disparate Data sources:You can work by connecting to various data sources, data warehouses, and files stored in the cloud.
• Adding Datasets: Tableau allows the easy addition of new datasets, which automatically blends with the Tableau.
