Distributed Component Object Model definition
<programming> (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.

Distributed Computing Environment definition
(DCE) An architecture consisting of standard programming
interfaces, conventions and server functionalities
(e.g. naming, distributed file system, remote procedure call)
for distributing applications transparently across networks of
heterogeneous computers. DCE is promoted and controlled by
the Open Software Foundation (OSF).

Distributed Data Management definition
<protocol, database> (DDM) An IBM data protocol
architecture for data management services across distributed
systems in an SNA environment.
DDM provides a common data management language for data
interchange among different IBM system platforms.
Products supporting DDM include AS/400, System/36,
System/38 and CICS/DDM.
On the AS/400, DDM controls remote file processing.
DDM enables application programs running on one AS/400
system to access data files stored on another system
supporting DDM. Similarly, other systems that have DDM can
access files in the database of the local AS/400 system.
DDM makes it easier to distribute file processing between two
or more systems.

Distributed Logic Programming definition
<language> (DLP) A logic programming language similar to
Prolog, combined with parallel object orientation similar
to POOL. DLP supports distributed backtracking over the
results of a rendezvous between objects. Multi-threaded
objects have autonomous activity and may simultaneously
evaluate method calls.

<architecture> The kind of memory in a parallel processor
where each processor has fast access to its own local memory

message via the inter-processor network.

distributed system definition
A collection of (probably heterogeneous) automata whose
distribution is transparent to the user so that the system
appears as one local machine. This is in contrast to a
network, where the user is aware that there are several
machines, and their location, storage replication, load
balancing and functionality is not transparent. Distributed
systems usually use some kind of client-server organisation.
Distributed systems are considered by some to be the "next
wave" of computing.
Distributed Computing Environment is the Open Software
Foundation's software architecture for distributed systems.
