The Big Data Era has made Data Science to become an extremely promising field for young aspirants and for those with a keen interest in computer science.

What is Data Science?

Data Science is a discipline which is consisting of studies related to statistics, mathematics, programming, computer science and so on. Data science requires several elements, techniques and theories including math, statistics, predictive analysis, data modeling, data engineering, data mining, and visualization.

Data Scientist understands the exploratory analysis to discover information from it and uses various advanced machine learning algorithms to identify the occurrence of a specific event in the future

So, Data Science is primarily used to make decisions and predictions making use of predictive causal analytics, prescriptive analytics (predictive plus decision science) and machine learning.
