       Distributed Component Object Model (COM, MS, OLE, ActiveX)


The Free On-line Dictionary of Computing (30 December 2018):

Distributed Component Object Model
DCOM

    (DCOM) Microsoft's extension of their
   Component Object Model (COM) to support objects distributed
   across a network.  DCOM has been submitted to the IETF as
   a draft standard.  Since 1996, it has been part of Windows
   NT and is also available for Windows 95.

   Unlike CORBA, which runs on many operating systems, DCOM
   is currently (Dec 1997) only implemented by Microsoft for
   Microsoft Windows and by Software AG, under the name
   "EntireX", for Unix and IBM mainframes.  DCOM serves
   the same purpose as IBM's DSOM protocol.

   DCOM is broken because it's an object model that has no
   provisions for inheritance, one of the major reasons for
   object oriented programming in the first place.
