It is necessary to take into consideration what data science and big data can do for the average citizen in order to provide an answer to the question of why data science is important. The results of data science are already working their magic in our day-to-day lives so that we can answer the question. Consider, for example, the internet. a greater number of webpages than one could possibly fathom (a quick google search suggests 1 billion which is a figure that is actually hard to imagine). In the background, data science is trying to filter through the one billion webpages that Google searches through in order to provide you with the information that you are looking for whenever you use Google to do a search. Through the use of data science, we have Facebook and Twitter. Researchers are working on developing personal monitoring devices for the purpose of improving our own health. These gadgets might potentially notify medical professionals and emergency services in the event that anything potentially harmful occurs, such as a heart attack. We would like to inform you that we are in the process of developing an online careers portal called bigdatajobs. This portal is intended for individuals who are either interested in working in the field of big data or who are currently employed in the field and are looking for careers that are specifically related to the fields of data science, machine learning, deep learning, data analytics, big data, and statistics. Please send an email to info@datasciencecareer.co.uk if you would like to be included to our email list in order to get information about employment possibilities and other relevant updates.
