I am making a javafx application for calculating ingredients and saving to a PDF file. The database will use sqlite. Tell me what resources to take for its correct construction?

Good afternoon!
Basically, you've already answered your own question. Use javafx, sqlite and any library for working with pdf (for example, iText - link )
Well, for example, for convenience, you can connect ORM to work with the database. For example, ormlite
For the beauty of the interface, you can use JFoenix
