OMA (Object Management Architecture)
Client: the user application using services.
Dynamic Invocation Interface: allows clients to use objects without compile-time knowledge of their interfaces. This is an advanced feature and will not be covered in this tutorial.
Static Invocation (Stub): generated by the IDL compiler to provide a "proxy" to an object to make it appear local to the client.
ORB (Object Request Broker): the communications system which passes requests to objects, and results back to clients.
Object Adapter: provides services to implementations (e.g. registration, management of object's lifetime).
Static Skeleton: generated by the IDL compiler to invoke the implementation using a set of conventions.
Dynamic Skeleton: special ORB functionality which allows invocation of implementations without compile-time knowledge of their interfaces. This is an advanced feature and will not be covered in this tutorial.
Implementation: code to implement the object.
