For maintenability, it’s better to cut the application technically.
* Model, contains only bean (getter/setter object). Model doesn’t contains other code (no business rules, no db request etc). Model can describe integrity constraint.
* Repository contains only the db request. It complete object of Model and send it to Service. Repository doesn’t know Service
* Service contains all the business rules. It knows Model and Repository
* We separate API`and `gui to deliver your api or gui separately.
