Distributed Object Middleware: An Introduction

Published: 10 January 2001

ID: G0090666

Analyst(s): Deborah A. Hess

Summary

Modern enterprise and Internet-based applications offer multitiered, component-based architectures that incorporate middleware for distributing components across multiple platforms. This middleware is customarily built using one of three architectures--the Object Management Group's CORBA, Microsoft's COM, or Sun's Java RMI or EJB. While Java and CORBA architectures are similar enough to interoperate easily, Microsoft's COM is relatively incompatible with the other two. A fourth technology, transaction monitoring, is simultaneously being absorbed by Java and CORBA middleware and emerging as a stand-alone product category by Microsoft.
