ETL roles primarily focus on data extraction, transformation, and loading, while Data Science roles involve advanced data analysis and modeling to derive insights and predictions. To bridge the gap, professionals can build expertise in statistics, machine learning, and data analytics through relevant courses, gain experience in working with more complex data, and collaborate on data-driven projects to apply ETL skills in a broader data science context.
