CORBA is a standard proposed by the Object Management Group (OMG) that promotes interoperability between distributed object systems. Following the standardization of this object-oriented middleware, the OMG has specified a set of Common Object Services (COS) that are meant to serve as the building blocks of distributed CORBA applications. The COSes are specified using CORBA Interface Definition...

We are presently witnessing an important paradigm shift occurring in the area of information system construction, namely from object and component technology to model technology. The object technology revolution has allowed the replacement of the more than twenty-years old step-wise procedural decomposition paradigm by the more fashionable object composition paradigm. Surprisingly this evolutio...

The Object Management Group has recently adopted a specification to standardise interworking between Signaling System No.7 systems and CORBA-based systems. This specification defines two types of interworking mechanism: 1. Interworking between CORBA-based TC-User Application Entities (such as CORBA-based Service Control Points) and legacy TC-User Application Entities (such as Service Switching ...

From an informational management point of view, a class schema is a static representation in so far as it doesn’t model behaviour of managed system elements. Our approach aims at selecting works achieved by the Software Engineering domain (OMG/UML) so as to reach universal understanding : concretely, we defined an UML profile for CIM class modelling and we have used the OMG/UML Statechart diagr...

Modeling standards by the Object Management Group (OMG) enable the interchange of models between tools. In practice, the success of such interchange has been severely limited due to ambiguities and inconsistencies in the standards and lack of rigorous testing of tools’ interchange capabilities. This motivated a number of OMG members, including tool vendors and users, to form a Model Interchange...

ODRA (Object Database for Rapid Application development) is an objectoriented database management system provided as an integrated programming tool for building various business and administration applications, including centralized and distributed systems, Web applications, service buses, virtual repositories, P2P networks, and so on. The paper presents general architecture of ODRA, its object...

A workkow history manager maintains the information essential for workkow monitoring and data mining as well as for recovery and authorization purposes. Certain characteristics of workkow systems like the necessity to run these systems on heterogeneous, autonomous and distributed environments and the nature of data, prevent history management in workkows to be handled by the classical data mana...

In December 2000 the Object Management Group (OMG) called for a proposal of a smart transducer interface. In response a new standard has been proposed that comprises a time-triggered transport service within the distributed smart transducer subsystem and a well-defined interface to a CORBA environment. This smart transducer standard has been adopted by the OMG in January 2002. The smart transdu...
