Data analysis refers to the use of data to guide decision-making in a Business. This is achieved by sorting, structuring, and converting data to derive useful information with relevance to business functions.

This is something that we adopt on a day-to-day basis while making decisions. For example, when we make purchases, we tend to research to find the best price, quality, and standard of a certain product before making the purchase.

When the same premise is followed with the use of big data in a business decision, it becomes data analysis.
