I see. Thanks. I'd say data transformation is a part of feature engineering (commonly the bulk of the effort in a ML application). And exploratory analysis is part of model work. W/o those 2 one would be building a model out of dreams and wishes. Data Science is probably a poorly chosen description. I'd say common use includes infrastructure work which for most of us consists in engineering work.
