Think of driving a driverless automated car. Sounds ironic! Then let us assume travelling in an automated car. The car collects all the data from the sensors, cameras and other devices. Big Data coming into role here. The machine learning domain involved here decides the speed, direction of the car. Now this is data science in action. We just analysed a real time apllication of data science. Here the data of the car is being analysed and computed accordingly. This implies the definition of data science. Data Science is one of the top trending technology of the era and data science has stretched its roots deep down in the corporate industry.

Due to this vast inference, new age learners and working professionals are keen to learn this technology. To curb this, various online data science certifications are available through which one can master data science and begin career as a data scientist.

Let us analyse another real time application in which data science is involved in predictive analysis. Weather forecasting is a predictive analysis where machine learning domain of decision making comes into action. The data is collected from the ships, aircrafts, radars and satellites and analyzed to give a weather report. What is the decision making scenario here? What is there to predict something here? The answer is, to predict the occurance of any natural calamities like cyclone, tornadoes and many more. The machine learning capability gives the calamity occurance report. The results are predicted by decision making domain which is a part of data science. The collection of data, analyzing it, computing the data and giving out results, this is Data science. So when you hear a bad weather day on news, thank a data scientist. 

So far we have seen data science in action. Now let us explore what data science is and what are the computer science domains involved in data science. 

Data science is the blend of data involved domains of computer science like machine learning, big data and so on. Data science involves many machine learning algorithms for predictive analysis, decisions. 

It is as simple as that, play with data, produce some results. Bingo! You have just worked on data science. Explore deeper, your designation turns out to be called as a Data Scientist. You run the world. Data Science, the revolutionary discovery in computer science the current world relies on.
