I've heard those terms multiple times but never actually thought about their origin or proper use.
Researching class naming conventions and concerns separation I found references to Clean Architecture book by Robert C. Martin.
Listing the terms I've selected to introduce for the Team
- Model (Entity, Aggregate) - a representation of a business entity. Encapsulates associated business logic. Typically responsible for persistence.
- Domain Service (Interactor) - domain logic that relies on two or more entities.
- Use Case (Application Service) - a list of actions or event steps typically defining the interactions between a User and a system to achieve a goal.
- Gateway - an adapter between the application and a 3rd party API.
