Data Engineers, Data Scientists, Machine Learning Engineers, and so on. Out of so many exciting roles, how do you decide the perfect fit for you? Let's simplify this by knowing what all each entails! As seen in the infographic, the data science process typically goes from data collection and cleaning to model building and final deployment. Data engineers are primarily involved in the first two phases, where they are tasked with designing & implementing data collection and storage systems. Once data is cleaned for inaccuracies, it is used to train, validate and deploy models by Data Scientists and Machine Learning Engineers. Business analysts also take part in interpreting model results for decision-making. You, too, can claim a top data science role for yourself with the best data science master's programs.
