Data science is an in-demand career path for people with an aptitude for research, programming, math, and computers. Discover real-world applications and job opportunities in data science and what it takes to work in this exciting field.
Data science is an interdisciplinary field that uses algorithms, procedures, and processes to examine large amounts of data to uncover hidden patterns, generate insights, and direct decision-making. Data scientists use advanced machine learning algorithms to sort through, organise and learn from structured and unstructured data to create prediction models.
The Government of India launched a programme in 2015 called Digital India with the mission to increase digital access and promote digital growth across the country. As the relevance and accessibility of big data have skyrocketed, there is a growing need for professionals who can work with the data available and make tangible impacts. Because of this, data science offers a variety of job opportunities—from researching to computing.
In this article, you will learn about how data science is used in the real world, salary expectations for jobs in the field, its required skills, and what credentials you need to land a job.
Data science is the study of data, much like marine biology is the study of sea-dwelling biological life forms. Data scientists construct questions around specific data sets and then use data analytics and advanced analytics to find patterns, create predictive models, and develop insights that guide business decision-making.
Although data science is often concerned with making sense of abstract data points, its impact can be seen concretely throughout the world today. Here are some familiar examples of data science or data science-powered services found all around us:
Data science models are essential in modern advertising, from display advertisements on numerous websites to digital posters at airports.
One of the most common ways that data science is employed in marketing is when you Google a term, and algorithms create relevant search results, including targeted ads related to your query. This application of data science is why you may see an online advertisement for data science training programmes, while someone else in the same region may see an advertisement for clothes.
Businesses can customise them based on the user's previous behaviour. This is why digital advertisements have a far higher CTR (call or click-through rate) than traditional advertising. Many marketing firms have taken advantage of data science to promote their offerings based on users' interests and data relevance to enhance customer engagement. Companies like Amazon, Twitter, Google Play, Netflix, and others also adopt this strategy.
Data science applications are especially beneficial to health care, where it's used for a wide range of purposes, including:
Medical image analysis
Genomics and genetics
Pharmaceutical research and development
Bots for health and virtual assistants
Even medical operations have benefited from data science innovations. Employing various methods and frameworks, such as MapReduce, data science is used to identify malignancies, artery stenosis, and organ demarcation. Support vector machines (SVM), content-based health care image indexing, and wavelet analysis are machine-learning approaches used to classify solid textures.
Data science implementations also provide a better level of therapy customisation via genetics and genomics analysis. The goal is to identify particular molecular linkages between genetics, disorders, and pharmaceutical responses to understand better how DNA affects human health.
Data science techniques and artificial educational algorithms ease and streamline pharmaceutical R&D, giving a new perspective at every stage, from the initial screening of medicinal substances to forecasting the rate of success based on biological characteristics.
Besides "lab tests," these algorithms use sophisticated mathematical modelling and simulations to forecast how a drug will react inside the body. Algorithmic drug development aims to create computational prediction models in the form of a biologically suitable network, making it easier to predict future outcomes with high precision.
AI-powered mobile applications, such as chatbots, can give basic health care assistance. Simply describe your health concerns or ask any health-related questions, and you'll receive critical information on your health status based on a large network of clinical symptoms and signs.
Data science has impacted e-commerce in various ways, helping businesses identify their target market, anticipate goods and services, and optimise price formations. Natural language processing (NLP) and recommendation engines, in particular, have proven highly beneficial to e-commerce companies that employ these methodologies to analyse customer purchases and gain insight into potential growth strategies. Furthermore, NLP is used to analyse texts and online surveys, which helps businesses provide quality services to their customers.
Data science has been at the centre of some of the most impactful innovations in transportation over the past two decades.
While self-driving vehicles are likely the most eye-catching data science development in transportation, data scientists have also been foundational to producing fuel usage statistics, analysing driver conduct, and monitoring vehicular performance. By combining reinforcement learning with automation, car manufacturers may create smarter, safer vehicles with better logistical routes.
Prominent ride-hailing apps like Ola use data science to optimise cost and completion routes by combining various elements like customer behaviour, location, economic data, and logistic providers.
Airlines, meanwhile, use data science to predict delayed flights, choose which aircraft to purchase, plan routes, manage flight delays, and create loyalty programmes.
According to Glassdoor, the mean annual salary for data scientists is ₹14,00,000 in India [1]. However, reported salaries range from ₹8,00,000 to ₹21,00,000 depending on location, experience, company, and job responsibilities.
Many jobs are in the field of data science. Some of the most common positions include:
Data analyst
Machine learning engineer
Data engineer
Data scientist
Database administrator
Business analyst
Product analyst
Financial analyst
Data system developer

HTML (HyperText Markup Language) is the most basic building block of the Web. It defines the meaning and structure of web content. Other technologies besides HTML are generally used to describe a web page's appearance/presentation (CSS) or functionality/behavior (JavaScript).
No matter what your service or product is, you need to get in front of potential customers in order to make the sale. Many businesses put their faith in social media.
It is. In fact, there are about 4.9 billion global internet users as of 2021, a 400 million jump from 2020. And although we say it a lot, the way people shop and buy really has changed along with it — meaning offline marketing can’t be your only strategy for driving sales because you need to meet audiences where they’re already spending time: on the internet.
