I’m learning MAUI by myself, and I still have question marks about datas and how to use them respecting best practices.

I have seen how to use SQLite which is nice when we need local datas recording, but what if we want some of those datas to be on a online database.

I first asking what is the best online database server technology to use?
And how to sync these datas with the online database?

There are plenty of tutorial and documentation on how to use datas in MAUI but I would better like to have your skills advices.

Thanks in advance.
