Relationships with Hibernate Reactive and Vertx

In the 4th part of my Hibernate Reactive & Eclipse Vertx tutorial, we cover an important topic of relationships. Relational databases, as PostgreSQL or MySQL make use of table relationships in order to store complex data structures. We talk about common types of relationships (one to one, one to many, many to one) and how they are implemented with JPA and Hibernate. We add a new data model to our application and finally we create an integration test to verify that our code does work correctly.
