@hamje32 - I should point out that not everyone who interacts with the data is a developer. If you’re an analyst the data analysis models listed here are of limited usefulness.
I suppose the most useful one mentioned is the physical data model, knowing how information is stored in the database. You won’t be doing object oriented programming as an analyst.
You get down in the muck and mire of the data itself, writing queries and creating reports. At least that’s what I did when I was an analyst.
