I. Introduction
Data Science is an analytical field of study that uses data mining tools, machine learning algorithms and big data to extract knowledge from structured, semi-structured data and unstructured data. It combines the concepts of statistics, data analysis and their related methods to understand the actual circumstance of data. Based on the analysis done on data, frequent patterns can be found and predictions can be made based on these results.
