The CORBA Component Model, Part 1

This column is the first in a series that focuses on the CORBA Component Model (CCM). It first outlines the evolution of programming abstractions from subroutines to modules, objects, and components. Then it describes how this evolution has largely been mirrored in middleware, from message passing to remote procedure calls and from distributed objects to component middleware. Finally the article discusses the limitations of distributed object computing (DOC) middleware that motivate the need for component middleware in general and the CORBA Component Model (CCM).
