Data engineering is not data science. Data engineers deliver the data for data scientists, data scientists use the data in models.

This does not follow the typical programming "cookbook" structure, but it is a real thing in naming books. Like a conventional cookbook, a programming one has lots of examples and "recipes" for how to solve common problems, but doesn't necessarily provide the knowledge to be able to recognize or understand those problems.

Like how almost no recipe book would tell you that it's customary to serve cake on birthdays or that you should be careful of the high sugar, or various cake alternatives, you would just find a section for cakes and it assumes you're making the correct choice in searching for a cake recipe.

For example I own a cookbook on NLTK and flipping to a random page I got "How to remove insignificant words from a sentence"

Are you referring to the term "data engineering" or the word "cookbook"?
