Data science is a combination of various tools, algorithms and machine learning principles aimed at discovering hidden patterns of raw data. As you can see in the image above, a data analyst usually describes what is happening by processing the data history. Data scientists, on the other hand, not only perform exploratory analysis to discover insights, but also use various advanced machine learning algorithms to detect the occurrence of a particular event in the future. A data scientist looks at data from different angles, sometimes from angles that have not been addressed before. Thus, data science is primarily used for decision making and prediction using causal analysis (prediction), prescriptive analysis (prediction plus decision making), and machine learning.
