Nowadays, Business continuity management (BCM) has become an important topic in most sectors of activity, for government organizations as well business owners and their stakeholders, especially after the pandemic COVID-19. For years, companies have been working on BCM strategies to deal with disruptive events like floods, terrorist attacks, pandemics. As environment is becoming increasingly com...

The Unified Modeling Language (UML) is the de facto standard for designing models of software systems in both industry and academia. UML has many advantages, and is often the tool of choice when conveying information between various stakeholders. UML’s main disadvantage is that it is too abstract – resulting in ambiguous models. In safety critical systems, ambiguity could result in the loss of ...

The tighter coupling of enterprises in regard to information system technology has also changed the way business processes are modeled. Modeling interorganizational business processes is necessary in order to gain a profound and unique representation of the processes involved. However this requires a new methodology especially designed for modeling inter-organizational business processes. The U...

This paper discusses platform independent conceptual modeling of a knowledge intensive application, focusing on the use of knowledge-based systems (KBS) in the context of model-driven engineering. An extension to the Unified Modeling Language (UML) for knowledge modeling is presented based on the profiling extension mechanism of UML. The UML profile discussed in this paper has been successfully...

The need for a Unified Enterprise Modelling Language (UEML) that would be used as in inter-lingua among enterprise modelling software tools has been established. The process of defining this UEML goes through the elaboration of a precise meta-model describing the constructs of the language. A possible and reasonable approach for the definition of this meta-model is to integrate (parts of) meta-...

In Software Engineering classes, students need to learn how to use Unified Modeling Language (UML) in the software design process. In this paper, we describe a sketch-based software tool called SketchUML that allows students to create UML class diagrams as naturally as they would on paper, but with the editing capability provided by software. We describe the design choices made in SketchUML for...

Ever since the introduction of computers into society, researchers have been trying to raise the abstraction level at which we build software programs. We are currently adopting an abstraction level based on graphical models instead of source code: MDE. MDE is the driving force for some recent modeling languages and approaches, such as OMG’s UML or Domain-Specific Modeling. All these approaches...

This paper introduces a visual, UML-based notation for OWL ontologies. We provide a standard MOF2 compliant metamodel which captures the language primitives offered by OWL DL. Similarly, we invent a UML profile, which allows to visually model OWL ontologies in a notation that is close to the UML notation. This allows to develop ontologies using UML tools. Throughout the paper, the significant d...

For conceptual information analysis, the object-role modeling (ORM) approach is arguably more suitable than entity-relationship modeling and the class modeling technique within the Unified Modeling Language. Although ORM has been used for three decades and now has industrial modeling tool support, it has no official, standard meta-model. Because of its extensive capability for expressing busine...

The Unified Modeling Language (UML) is commonly used in Computer Science curriculum in order to teach object oriented analysis, design and programming. In this context, UML CASE tools are useful to assist in modeling and automating routine tasks. However, available tools are generally intended for use by professional developers to improve productivity and are not suitable for educational purpos...
