Help with Vaadin 14 as a UI for mariaDB

I am very new to Vaadin and I’ve been trying for over a week to make a UI for a mariaDb. Does anyone know a good up to date tutorial on how to display data from an external database? I’ve found a lot of old tutorials but they all use prebuilt projects or are super out of date.

If nothing else I’d love to ask a few specific questions to anyone who is willing to answer.
