What is Data Science, and What is the Role of a Data Scientist?

Data science is a complex process in which collected data is cleaned and analyzed to improve decision-making. Data cleaning and analysis, when done on the enterprise level, requires using high-level algorithms and statistics. Simple examples of data science include Netflix recommendations, personalized shopping recommendations on Amazon, and fraud detection in banking using patterns. Data science has many other applications in the modern digital world, where most businesses and enterprises are utilizing data to improve the overall efficiency of their services.

The role of a data scientist is to help businesses make data-driven strategic decisions by leveraging algorithms, data modelling, and data visualization. Moreover, they conduct in-depth data analysis to identify patterns and trends, which is highly beneficial for understanding market and consumer demands. Thus, every enterprise/organization, whether small, medium, or large scale, is always in search of trained data scientists with hands-on experience.
