Big Data vs Data Science

The tremendous increase of information available online has resulted in the need for Big Data. Big Data is the collection of large and complex data, which is not collected in the traditional methods we know; like graphs, charts, etc. Data Science, on the other hand, is the process of extracting insights from big data with a scientific approach to help businesses make decisions.

In this article, we will discuss the key differences between Big Data and Data Science, while comparing the objectives, skills, tools, and careers in both fields.

Difference between Big Data and Data Science

The main difference between Big data and Data Science is that Big Data needs to be studied by businesses to understand the scope of improvement and competitiveness while to study big data, Data Science is needed which draws insights using mathematics, statistics, and computer science.

Similarities and differences between big data and data science

Big data and data science are intertwined realms in the vast landscape of data handling. Both converge on extracting value from data. Big data primarily refers to the immense volumes of data—structured and unstructured—that traditional databases can’t handle. Its focus is on storage, processing, and retrieval. Data science, on the other hand, is a broader domain that encompasses a range of techniques to analyze and interpret that data, including but not limited to big data. While big data lays the foundation by managing voluminous data sets, data science dives deeper, leveraging algorithms and analytical methods to derive actionable insights from them. In essence, big data provides the canvas, and data science paints the picture.

Benefits and uses of big data and data science

Data science and big data, when combined, become a powerhouse for organizations in the modern era. Big data provides the capability to harness vast and varied datasets, capturing nuances from myriad data points. Data science, leveraging this richness, uses advanced algorithms and models to extract actionable insights, patterns, and predictions. The benefits are manifold: businesses can tailor marketing strategies with precision, forecast trends, optimize operations, and even enhance user experiences in real-time. From healthcare, where patient care is personalized, to retail, where shopping experiences are customized, the fusion of data science and big data is revolutionizing industries and driving innovation at an unprecedented pace.

In the digital era, the need of data science and big data is indispensable. As data proliferates, big data manages the deluge, while data science translates it into actionable insights. Their synergy is vital, enabling businesses to navigate the information tide, make informed decisions, and harness the era’s true potential.

What is Data Science?

Where Big Data is related to collection and processing of Data, Data Science is a multidisciplinary process which involves Mathematic, statistics, programming, analytics, Machine Learning, Artificial Intelligence and deep learning along with other scientific methods to gain information from data. The lifecycle of Data Science involves data extraction, maintenance, cleansing, modelling and presenting to businesses.

For example, In a cab service system Data science is used on multiple levels for incorporating maps for the route, cost of the drive, information about drivers, transport areas customer experiences, etc.

Skills required in Data Science

A few skills required in data science are

  • Programming skills like SAS or R.
  • Coding skills like Python, Java C/C++, etc.
  • Working with SQL for complex queries.
  • Working with unstructured and other types of data.
  • Deep learning and Machine Learning

Tools used in Data Science

Data Science involves multiple areas of work around data which requires various tools and systems. The process includes creating algorithms, storing, processing, cleansing, analyzing, and presenting data. As Big Data is a subset of Data Science, the tools used in Big Data are also a part of Data Science.

Some of the common tools used in Data Science are

  • R, Python, or Julai for algorithms
  • Winpure, Data Ladder for data cleansing and processing
  • PowerBI, Tableau, or Google Data Studio for data visualization.
  • Spark, MATLAB, and TensorFlow along with many other tools are used.

Career in Data Science

According to the US Bureau of Labour Statistics, 31 percent or more of growth is estimated in Data Science jobs by 2030. The high demand, lack of professionals, and higher salaries are a few points to consider while looking for a career in Data Science.
