What is Tableau?
Tableau is a data visualization tool most commonly used in the Business Intelligence and Data Science industry. It aims to help people view and understand complex data.
In today's world, data is one of the greatest assets of businesses. Nearly all industries and businesses rely on big data analytics to make informed decisions about their business. After big data from disparate sources is analyzed, it's often in the forms of statistics and numbers. This data needs to be presented to stakeholders and CEOs in a simple, visually appealing, and easily understandable format.
How does Tableau work?
- Tableau connects and extracts data stored in various locations, platforms, or databases like Excel, PDF, Oracle, etc.
- Then it is launched to start the process. Now you can connect to any database through Tableau's data connectors.
- After connecting to the databases, data is extracted and then connected live to Tableau Desktop, the Tableau data engine. Here, a data analyst or data engineer works on the data and develop the visualization. The final product includes dashboards, which the users can view using Tableau Reader.
