One of the things I'm constantly baffled by given the growth of data science and analytics is that data modelling isn't treated as a first class concern. It's absolutely fundamental to doing quantitative work efficiently at an organization with any amount of complexity, yet the majority of people in the field seem to be unaware of the concepts.
This ignorance is especially surprising given that it's essentially a solved problem (Kimball), yet if you talk about data modelling, people usually think regression, not schema.
