  object (computing) - Hutchinson encyclopedia article about object (computing)   (Site not responding. Last check: 2007-11-07)
In computing, an item created on a page in desktop publishing and many office applications.
Each object is housed in a frame and can be moved independently from the other objects on the page.
Objects can be reordered so that items can be brought to the front or sent to the back.

 Distributed Object Computing
The objects may be distributed on different computers throughout a network, living within their own dynamic library outside of an application, and yet appear as though they were local within the application.
Object wrappers (object-oriented interfaces to legacy code) may be applied to various computing resources throughout a network to simplify the means of communicating with these resources.
Distributed object computing is a computing paradigm that allows objects to be distributed across a heterogeneous network and allows each of the components to interoperate as a unified whole.

 Object - Computing Reference - eLook.org
In object-oriented programming, an instance of the data structure and behaviour defined by the object's class.
Each object has its own values for the instance variables of its class and can respond to the methods defined by its class.
For example, an object of the "Point" class might have instance variables "x" and "y" and might respond to the "plot" method by drawing a dot on the screen at those coordinates.

 Encina Object-Oriented Programming Guide
In distributed object computing, objects can be located across a variety of platforms and in different processes and can communicate transparently with each other (by issuing method requests) as if they were located on a single machine.
They can bind to individual objects when the objects are known, or they can bind to a class when the objects are not known or when all objects of a specific class provide the same capabilities.
After the client proxy object is bound to the server object, each member function call made on the client proxy object invokes an RPC to the server object, which executes the procedure and returns results to the client proxy object.

 EDOC 2005
The EDOC Conference is the primary annual event focusing on the convergence of the paradigms, technologies and methods involved in enterprise computing.
Today the creation, operation and evolution of enterprise computing systems raise concerns that range from high-level requirements and policy modelling through to the deployment of specific implementation technologies and paradigms, and involve a wide (and ever growing) range of methods, tools and technologies.
The themes of openness and distributed computing, based on services, components and objects, provide a useful and unifying conceptual thread for this purpose.

 OOP - a Whatis.com definition - see also: object-oriented programming, object-oriented   (Site not responding. Last check: 2007-11-07)
Examples of objects range from human beings (described by name, address, and so forth) to buildings and floors (whose properties can be described and managed) down to the little widgets on your computer desktop (such as buttons and scroll bars).
The first step in OOP is to identify all the objects you want to manipulate and how they relate to each other, an exercise often known as data modeling.
Once you've identified an object, you generalize it as a class of objects (think of Plato's concept of the "ideal" chair that stands for all chairs) and define the kind of data it contains and any logic sequences that can manipulate it.

 The Component Object Model   (Site not responding. Last check: 2007-11-07)
Objects in one process could not communicate with objects in another process using their own defined methods.
The OS takes the responsibility of creating objects when they are required, deleteing them when they are not, and handling communications between them, be it in the same or different processes or machines.
Distributed Computing purists will attest to the fact that marshalling is the process of packaging and transmitting data between different address spaces, automatically resolving pointer problems, preserving the data’s original form and integrity.

 Methods for Distributed Object Computing
Although most object methodologists have adopted use-case models as the basis for user-centered requirements analysis, there is considerable variance in how they adapt the use case concept and integrate it with the rest of their object models.
A client object sending a message to a server object need not concern itself about whether the server object is located at a nearby physical memory address or is located somewhere remote in cyber-space.

 Distributed Object Computing (Linktionary term)
As discussed under the topic "Object Technologies," objects are encapsulated procedures and/or data, a building block of reusable code that can be combined with other objects to create programs or add functionality to existing programs.
Some objects are used throughout the organization and may be the core components of an application.
But if components are running on different computers, they need a way to communicate the results of their work or problems that have occurred.

 Center for Distributed Object Computing, University of California, Irvine
The primary goal of this lab is to support advanced R&D on distributed object computing middleware using an open source software development model.
For the Internet to become pervasive, access devices must become very cheap, their use must be intuitive, and distributed computing middleware must do most of the ``thinking'' for the users.
This evolution will turn the current computing model inside out -- clients will become very thin, the intelligence will reside in the network, and most applications will be network-centric.

 Distributed Object Computing with CORBA   (Site not responding. Last check: 2007-11-07)
In the CORBA world, older technologies for distributed computing such as sockets or remote procedure calls are made obsolete.
Instead, all interactions are between (possibly distributed) objects, implemented in various languages and running in a variety of environments.
While some background in both object-oriented concepts and distributed computing will be helpful, none is required, although knowledge of the C programming language is strongly recommended.

 M206 Computing An Object Orientated Approach
M206 also teaches electronic computer conferencing if you have not used this method before, it uses the OU's FirstClass conferencing system to work in groups using electronic conferencing.
The M206 course uses the object-oriented view of software development, which basically means that each part of the software is considered an object and the completed software is a collection of objects that interact by sending messages to each other and reacting to the answers to the messages (senders and receivers).
The M206 course itself deals with Object-orientated programming using the Smalltalk language, the second part of the course has been changed since I took it and it now introduces Unified Modeling Language UML and since this is used in M301 it is an ideal way to prepare for M301 which uses Java.
