Data Science in its simpler terms is about generating critical business value from the data by various creative ways. It can also be defined as a mix of data research, algorithms and technology in order to solve complex analytical issues. Data is being by generated by Companies at an exponential pace. The usable Data form can be different for different section of people working in an organization. Data Science helps us to explore the data to the granular form and find the needed insights. Data Science is about being analytical or inquisitive wherein asking new questions, doing new explorations and keep learning is a part of job for Data Scientists.
