Data has been significantly increased due to the rise in internet usage. Think about a scenario where each time a potential customer gets online, you add their data to big data. This material contains details that could be very useful for your company. It would be best if you had business intelligence—meaningful insights into the behavior and preferences of your potential customers—to remain one step ahead of the competition. It will enable you to address them more effectively. Big data generates this information.

But because it is in an unstructured, raw state, this large amount of data is wasted. Understanding and thoroughly analyzing this data can be challenging, so each organization's stakeholder knows it. You must also present your data in a way that even a layperson with no technical knowledge can comprehend because only some possess the necessary technical expertise for data analytics. Tableau aids you in accomplishing this.
