You will need a database to save the information. If it is a robust application, I recommend postgresql with the pgAdmin along with pgModeler to make relationships visually. Now if you prefer you can use a very fast database, I recommend MySQL using the Workbench.
I advise using JPA as the API, which is a convention of how you should implement your providers . In this case I recommend Hibernate.
Do not be in a hurry to learn, learn the concepts in a solid way. I'm currently studying all this as well.
