Object request brokers

CORBA (Common Object Request Broker Architecture) was designed by the Object Management Group (OMG) to support open distributed communication between objects across a wide variety of platforms and languages. Interestingly, despite the Object in its name, CORBA does not directly expose the notion of object identity it could more properly be considered a distributed component framework. [Pg.426]

Other cycles can be horizontal one that does not deliver new user-visible functionality but instead carries a minimal use case through increasingly deep layers of the application and infrastructure components, exercising all communication channels. An example is a single user interaction carried from the user interface through the business object layer via an object request broker (ORB) to the applicable databases and back. [Pg.561]

One of the drawbacks of JADE framework is that it does not support Ml mobility of agents. By default, JADE agents communicate with each other using Java Remote Method Invocation (RMI, [5]) or Common Object Request Broker Architecture (CORBA, [6]). However, a mobile agent can be created and it can travel between hosts within the same agent platform but not between different platforms. Currently, there is a research work on going to enhance JADE to support mobility between different agent platforms. [Pg.334]

The management system relies on the Common Object Request Broker Architecture (CORBA) to deal with the problem of heterogeneity. CORBA is a prominent example of a distribution platform [877]. The CORBA architecture consists of five functional areas [1024] ... [Pg.403]

It should be noted that different concrete architectures for one logical architecture exist in general. These may reflect a sequence of possibly different interdependent decisions of the above list, or different realization variants. For example, one concrete architecture may be equipped with a RPC and another one with a CORBA (Common Object Request Broker Architecture [877]) implementation of interprocess communication. [Pg.563]

Needless to say, there are other ways to exchange data like the Common Object Request Broker Architecture (CORBA) (15). This standard provides an intermediary object-oriented layer that handles access to the data between server and client. Another recently emerging way to exchange data is web services (16), which will be described later. [Pg.196]

The Object Management Group, a consortium of object technology vendors founded in 1989, created a technology specification named CORBA (Common Object Request Broker Architecture). CORBA employs an abstraction similar to that of RPC, with a slight modification that simplifies programming and maintenance and increases extensibility of products. [Pg.720]

The basic service provided by CORBA is delivery of requests from the client to the server and delivery of responses to the client. This service is realized by using a message broker for objects, called object request broker (ORB). An ORB is the central component of CORBA and handles distribution of messages between objects. Using an ORB, client objects can transparently make requests to (and receive responses from) server objects, which may be on the same computer or across a network. [Pg.720]
