As the world entered the era of big data, the need for its storage also grew. It was the main challenge and concern for the enterprise industries until 2015. The main focus was on building framework and solutions to store data. Now when Hadoop and other frameworks have successfully solved the problem of storage, the focus has shifted to the processing of this data. Data Science is the secret sauce here. All the ideas which you see in Hollywood sci-fi movies can actually turn into reality by Data Science. Data Science is the future of Artificial Intelligence. Therefore, it is very important to understand what is Data Science and how can it add value to business. Data Science is a field that covers data cleansing, preparation, and analysis. It is an umbrella term that includes several scientific methods, such as mathematics, statistics, and many other tools scientists apply to extract knowledge from data sets.

According to International Data Corporation (IDC), a technology research company, global data analytics and big data market is likely to reach USD 57 billion by 2020 with a CAGR of 23%. This also means that there is going to be a bigger gap in demand and supply of data scientists, including professionals for information management, software development, data analytics, artificial intelligence and data discovery. Hence, Python, R, SAS, Machine Learning etc. have become the most sought after skills.
