Distributed Object/Service Models
CORBA provides a uniform distributed object model
Today we see a more complex distributed heterogeneous server (as proxy for service) model which we view as a 3 tier architecture on next foil
COM from Microsoft is a similar model largely focused on PC’s with a richer (in terms of implemented objects) current implementation but a less elegant architecture
RMI from JavaSoft is cross platform distributed object model like CORBA but confined to one language (Java) whereas CORBA is multi-language and multi-platform
