Wait a moment. I didn't say what I don't understand because I most
certainly don't understand more than I do understand. So that's not
interesting to talk about.

That what I'm saying "could create a false dichotomy in your mind".

I want paint a different picture with more gradients.

It sounds like in this case the historical data is also useful.

So it's not your area of expertise. Understood.

Yes, that's what I stated as the main reason.

This seems again to being going in the direction of a false dichotomy.

A database like SQLite or BDB is not, well you know what I am about to
say, and I think it makes sense for the person asking to know about the
options.

If you are a really good programmer, my advice is probably not suitable
since you can just quickly rewrite everything.

Web? Probably not needed. Django, I personally don't like Python much. I
mean the type "system" is just a linter.

It sounds like maybe s/he wants some display (real time?). I can't give
much advice on libraries/tech for that... If you have small LCD or
remote computer with network connection, it would be quite different.

I recommend golang to new programmers. It's quick to get started with
and have good results. The standard tooling and library is very good.

https://github.com/go-echarts/go-echarts
https://pkg.go.dev/database/sql
https://gobyexample.com/
https://go.dev/doc/effective_go

There's so much out there. Just be careful for libraries that rely on
many more libraries. I would also say that for Python and JS. It seems
to be a symptom of a modern sickness.

Have fun!
