Difference Between Big Data And Data Science: Terms like “Big Data” and “Data Science” have become buzzwords – but what is the difference between Big Data and Data Science? While both the words may seem similar, yet they serve different purposes.
Let us explain more on the same here in this blog!
What Is Big Data?
“Big Data” refers to massive volumes of structured, semi-structured, and unstructured data generated by various sources like social media, IoT devices, e-commerce platforms, and more. The defining features of Big Data are the 3Vs:
- Volume: The sheer amount of data.
- Velocity: The speed at which data is generated.
- Variety: The different forms of data (text, images, videos, etc.).
Big Data tools like Hadoop and Spark help organisations store, process, and analyse this data to extract valuable insights. For example, when Netflix collects millions of user interactions daily, that’s big data in action.
What Is Data Science?
Data Science is a multidisciplinary field that combines statistics, programming, and domain knowledge to extract insights from data. While Big Data deals with the data itself, Data Science focuses on analysing this data to solve problems and make informed decisions. It involves processes like:
- Data cleaning
- Exploratory data analysis
- Machine learning
- Data visualisation
Popular tools for Data Science include Python, R, and Jupyter Notebook.
Fun Fact: Did you know that “Data Scientist” has been called the “sexiest job of the 21st century” by Harvard Business Review? Lol, it’s true!
What Is Big Data In Data Science?
Big Data refers to extremely large datasets that are complex, varied, and grow at a rapid pace. These datasets are so vast that traditional data processing tools and techniques struggle to handle them. In data science, Big Data is crucial because it provides the raw material for uncovering data, making predictions, and driving informed decisions.
How Do Big Data And Data Science Work Together?
Big data and data science often go hand in hand. For example, big data provides the raw material, while data science refines and processes it to generate actionable insights.
Consider this: Big data without data science is like a library without a librarian. The data is there, but you need a system to make sense of it.
What Is The Difference Between Big Data And Data Science?
Now let’s tackle the core question: What is the difference between Big Data and Data Science?
| Features | Big Data | Data Science |
| Definition | Handling large volumes of data | Extracting insights and making predictions |
| Focus | Storage, processing, and management | Analysis, modeling, and decision-making |
| Techniques Used | Hadoop, Spark, NoSQL | Machine learning, statistical modeling |
| Role | Provides raw data | Converts raw data into actionable insights |
| Professionals | Data Engineers, Big Data Analysts | Data Scientists, Machine Learning Engineers |
