The Comparison of CORBA,DCOM and Java/RMI

Distributed object technology mainly establishes application system skeleton and object components for a distributed heterogeneous network. Under the supports of the application system skeleton, developer can encapsulate the functions as an object, which can be managed and used more expediently. Those distributed objects in different platform can interoperate as a unified whole. At present, three of the most popular distributed object paradigms are OMG's Common Object Request Broker Architecture (CORBA), Microsoft's Distributed Component Object Model (DCOM) and JavaSoft's Java/Remote Method Invocation (Java/RMI). In this article, we will examine the differences between these three technologies, and appreciate the merits and innards of each of the distributed object technology from a programmer's standpoint and an architectural standpoint.
