What Is Data Science?

It is a field that deals with structured and unstructured data and comprises everything ranging from data cleansing, preparation to analysis.


Data science combines mathematics, statistics, programming, problem-solving, and collating data to look at things differently by aligning and analysing said data. Furthermore, data science is an umbrella term that encompasses various techniques used while extracting insights and information from data.


What Is Big Data?

Big data deals with massive volumes of data that cannot be processed effectively using traditional techniques. Big data processing begins when raw data is collated from multiple sources and is then stored in a single computer’s memory. Furthermore, it is used to analyse insights, leading to better, more efficient business decisions.


Now you know what these two domains entail. Let’s understand the fundamental differences between the two worlds.
