Distributed Component Object Model
<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 Data Management
Distributed Computing Environment
(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 database
A collection of several different databases that looks like a single database to
the user. An example is the Internet Domain Name System (DNS).

Distributed Data Management
<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
<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.

distributed memory
<architecture> The kind of memory in a parallel processor where each
processor has fast access to its own local memory and where to access another
processor's memory it must send a message via the inter-processor network.
Opposite: shared memory.

distributed system
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.
