Therefore, it is not surprising that Big Data is becoming one of those niches that are most actively developing and where the demand for qualified specialists is growing.

Data Scientists – The “Lords” of Big Data

The Data Scientist profession requires a combination of diverse knowledge from many fields. The ability to work with a large amount of information, knowledge of mathematics, statistics, and programming skills is a foundation that must be mastered. Besides, being a professional will help you to avoid online data entry job scams, as you will know how to sort the wheat from the chaff. However, before investing in studying, you should understand what kind of career possibilities and prospects you have. What industries need data scientists? know the role and responsibilities of the data scientist.

Working with big data analytics, you can analyze tourist flows and create new routes; help cities optimize traffic flows; introduce new airlines and passengers to airports; determine potential credit fraudsters, etc. In general, it means contributing to the optimization of almost any industry that can be digitized. The experience and skills of Data Scientists can be applied in a wide variety of industries: finance, retail, manufacturing, health care, environmental protection, and more. 

Practical Cases

Big data is a source of innovation. This is by no means news, but it does not make big data less important. They help companies move towards digital transformation. Here are some successful cases:


Of all the industries, telecom has best adapted to the vast amounts of data that telecommunications companies get through their networks. Mobile operators have information about user profiles, their devices, geolocation, behavioral patterns, etc. Major telecom companies such as AT&T, CenturyLink, Swisscom, T-Mobile, and Vodafone have already incorporated big data analytics into their software development. Thanks to this, they will be able to better predict demand, plan the load on their networks, and better understand their market.


With a world population of more than 8 billion people, climate change, and the depletion of farmland, modern agriculture faces serious challenges. To meet these challenges, the industry is embracing innovative technical developments such as the Internet of Things, cloud technologies, big data, and analytics. Using smart sensors and connected devices, Data Scientists are creating a new generation of “smart” farms based on the use of big data.


The scope of data analytics in finance and banking is huge. From internal structured data (trading systems, data from markets and stock exchanges) to unstructured data (social media, user feedback), financial institutions know how to use the information for their success. Credit risk assessment is one of the most important activities of financial institutions in the context of big data.


According to Global Big Data Analytics, the retail market will reach $14 billion in 2026, growing by 23.4%. This means that it will become more and more difficult to keep the attention of buyers among the variety of products. To succeed in an extremely competitive industry, merchandise sellers are using big data to help them better understand consumer behavior and become truly customer-focused.


Clinical research, digital medical records, and other MedTech solutions are markers of a real technical revolution in the field of healthcare. Thanks to big data, medical analysts achieve not just outstanding, but life-saving results. Based on medical data, doctors can more accurately diagnose and predict the course of the disease, which improves the quality of life of patients and saves their costs.

Big data enables businesses of all sizes to gain insights and discover hidden patterns. Working in this area is not only exciting, but it also represents a substantial investment in enhanced customer service and a better world.
