I started with experiment 1, but it was not clear what was ready in the tutorial and what needed to be done. As a result, I created a new persistence.xml, which made things difficult. This took a while to figure out, but with some help it went fine after that.
I struggled a lot with the database and that it would not run, but it did work after a while. I had mininterpreted where the database ended up, which complicated things. Implementing the methods, relationships and creating the database in itself went smoothly I felt.
I used the diagram and queries to inspect that everything was working with the database. I also ran the test case of course.
Here is a picture of my database
