So, what is data science all about ?, data science is an interdisciplinary field that uses scientific methods, processes, algorithms and systems to extract knowledge and insights from data in various forms, both structured and unstructured, similar to data mining.

A data scientist is someone who is better at statistics than any software engineer and better at software engineering than any statistician.

Data scientist is a composite from data analyst and data engineer, they have mindset to be an intuitive data addicts. They have must to role too, its collect the data, process and perform statistical data analysis, develop, build, test and maintain architecture (such as databases and large scale processing systems). Itsn’t just a buzz, a trend, or a fad, it’s revolutions that’s changing the world with it’s real impact.
