Everyone has heard of the buzzwords of the millennium – data science, data analytics, machine learning, big data, etc. But how many actually know what these terms mean? What their applications are? And how these terms are different from one another?
For a layman, there may not be a lot of difference, but when it comes to striving professionals looking to build a career in this domain, it’s key to understand the difference between big data and data science. This understanding will determine which courses they will pursue, a big data analytics online course or data science certification and what kind of jobs they’ll land.
So let’s help you discover the difference between these two domains so you can make the right career choice.
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.

1. Usage
Organisations use big data to enhance efficiency, understand their customer better, and increase competitiveness in the market. On the other hand, data science is used to provide modelling techniques and methods to evaluate the potential of big data in a precise manner.
Furthermore, data science uses theoretical and practical approaches to dig information from big data. Contrarily, big data is considered as a pool of data with no credibility unless analysed using data science techniques.
If you aspire to learn in-depth about big data and analytics, consider enrolling for a credible big data analytics online course. A data analytics course can help you understand the A-Z of the domain. However, if you aspire to build a career in the data science domain, you may enrol for business analytics courses online from a reputed institution like XLRI. The business analytics courses online from XLRI aims to provide a 360-degree understanding of business analytics, data analytics, and data science. What’s more, business analytics courses online from XLRI can also help you understand the difference between big and data analytics so you’ll have a better view of the domains.
2. Applications
Common Applications of Data Science

Retail
Whether it is a brick and mortar store or an online retailer, the answer to staying in the game and remaining competitive is to understand the customer better. And this requires the ability to extract and analyse customer data from all sources, including web blogs, transaction data, social media, etc.
3. Focus
Data science focuses more on decision-making areas of businesses, whereas the cornerstone of big data is technology, computer tools, and software. Big data analysis caters to a massive amount of data set, which is also known as data mining. However, data science uses ML algorithms to design and develop statistical models to generate information from the massive big data sets.
Fascinated by data science or big data? Not sure yet? Well, whichever domain you choose to build a career in, the pathway is clear. For a career in big data, a big data analytics online course is the ideal choice, and if you go down the data science path, you can consider enrolling in a credible data science course, or even a business analytics course can do the trick.
