CORBA: ORB, Services, Facilities
Previous slides illustrated software components involved in enabling remote method invocation for a single object
The next diagram categorizes various objects plugged in and playing on the CORBA bus
The system itself (i.e. ORB vendors) provides a set of base object services the Common Object Services layer and high level facilities
- facilities are called frameworks in Java
- horizontal facilities are generally useful
- vertical facilities are specialized to certain applications
Application objects built by users can refer to CORBA services/facilities as distributed OO libraries
