Need for Data Science

We hear a lot about the trends and applications of Data Science these days. Now, many questions would have already popped up in your mind such as: ‘Why do we need Data Science?’, ‘What is Data Science?’, ‘Is Data Science a good career?’, and ‘What are the trends in Data Science in 2021?

Let me answer these questions with a practical example. A few days back, I got a job offer through LinkedIn. The concerned HR of the company sent me an email regarding my interview timings. I overlooked the mail because I was quite busy. On the next day, a notification popped up on my mobile phone saying, ‘You have an interview scheduled at 1.30 pm today with Infosys,’ along with the location of the company. Then, I opened Google Maps on my phone to search for the location of the company. It was showing me the best route with less traffic to reach the destination. Isn’t it a great technology that assists us in reminding our important day-to-day tasks?
