Here is a quote from the book explaining a bank as a data
It’s an initial balance plus a set of transactions at a point in time. These transactions are functions.

users,productsandorders? -

For me, it often helps to put the database aside for a moment and figure out what data structures I really need. Once I have that, then I can ask myself how I would save it to a database.
Does that help get the ideas flowing?

This is the place that James and I always came back to throughout this book. “Let’s see how far we can get without persistence.”
We found that thinking about the solution in these terms shaped the way we thought about the problem.

We didn’t include users because the example is already complex enough and everyone shows users. We figured readers could tie that into their own designs.
I agree that simple CRUD is probably fine for your user models. I think the real trick is in getting products right.
