Move model to appropriate project #3
Description
The code regarding the domain model is currently being repeated in the frontend and backend projects. Such a practice should be avoided.
A good approach would be to define the model in a project apart, which would be inherited in the rest of the projects as needed.
Such an approach might be conflictive with Spring Boot, since Hibernate reads the model configuration in runtime from the model classes and having them in a different project might not work as expected.
