Data Science: The Famous Buzzword of Tech World


Data science is something that is used by almost every other industry today. The question is why? The answer is all the customer-oriented product creation. The data created by consumers and various entities involved in a business is huge. But then to understand and search for meaning inferences from them can be difficult. This is where data science helps, using various tools and algorithms to explore it and use it for strategic purposes.

The main objective of data science is to create value for the business. And value for business can be created by gauging the market risks and opportunity on time, knowing demands for new products and services, and most importantly customer satisfaction and retention.


It has a variety of applications in different industries. Industries indulged in it are:

  • Collecting data: involves collecting data from various sources and storing them in data frameworks.
  • Cleaning data: data usually have lots of flaws and gaps, these inconsistencies are to be removed and cleaned.
  • Exploring data: exploring data includes analyzing the data using visualizing tools and statistical models to find meaningful patterns.
  • Modeling of data: modeling usually involves creating algorithms using machine learning to use data as a strategic and predictive tool.
  • Communicating the results: this is where one needs to interpret the inferences and communicate with others so that it can be used for further business decision making.
