Many people perceive DCE and CORBA as competing technologies. Indeed,
both support the construction and integration of client-server applications
in heterogeneous distributed environments. Comparisons typically focus
on differences between individual capabilities or on differences between
the maturity of specifications and products that conform to them. There
is a fundamental difference between DCE and CORBA, however, that we
feel far overshadows either of these criteria as a basis for selecting
a distributed computing platform. This document summarizes the main
features of DCE and CORBA, presents what we feel is the most important
difference between them, discusses differences between individual capabilities
and the maturity of both specifications and products, and concludes
with our view of how an organization should select the technology most
appropriate to its distributed computing goals.
