Part I - Application Controller, Business Object, Composite Entity, Domain Store
posted 5 years ago
I'm preparing for my exam tomorrow, but still have some questions about new J2EEpatterns: Application Controller; Business Object, Composite Entity.
Does anyone have good examples on where these might be used and how and how
- Application Controller is different from Front Controller or Service to Worker. When one would use it.
- Business object different from Application Service, Composite Entity or Facade. When one would use it.
- Composite Entity is different from DAO or Domain Store (it says Composite Entity encapsulates the physical DB design). When one would use it.
- When one would use Domain Store?
