Towards a Definition of Role-related Concepts for Business Modeling
Abstract—While several role-related concepts play an\ud
important role in business modeling, their definitions,\ud
relations, and use differ greatly between languages, papers,\ud
and reports. Due to this, the knowledge captured by models is\ud
not transferred correctly, and models are incomparable. In this\ud
paper, we provide a meta-model and definitions for several\ud
role-related concepts based on the practice of existing modeling\ud
languages and ontological analysis. This forms a basis for\ud
creating comparable, formal business models, which enable\ud
further enterprise engineering, in a repeatable wa
A formal theory of conceptual modeling universals
Conceptual Modeling is a discipline of great relevance to several areas in Computer Science. In a series of papers [1,2,3] we have been using the General Ontological Language (GOL) and its underlying upper level ontology, proposed in [4,5], to evaluate the ontological correctness of conceptual models and to develop guidelines for how the constructs of a modeling language (UML) should be used in conceptual modeling. In this paper, we focus on the modeling metaconcepts of classifiers and objects from an ontological point of view. We use a philosophically and psychologically well-founded theory of universals to propose a UML profile for Ontology Representation and Conceptual Modeling. The formal semantics of the proposed modeling elements is presented in a language of modal logics with quantification restricted to Sortal universals
An Approach to Relate Viewpoints and Modeling Languages
The architectural design of distributed enterprise applications from the viewpoints of different stakeholders has been proposed for some time, for example, as part of RM-ODP and IEEE 1471, and seems now-a-days to gain acceptance in practice. However, much work remains to be done on the relationships between different viewpoints. Failing to relate viewpoints may lead to a collection of viewpoint models that is inconsistent, and may therefore lead to an incorrect implementation. This paper defines an approach that helps designers to relate different viewpoints to each other. Thereby, it helps to enforce the consistency of the overall design. The results of this paper are expected to be particularly interesting for Model Driven Architecture (MDA) projects, since the proposed models can be used for the explicit definition of the models and relationships between models in an MDA trajectory
MDA-based ATL transformation to generate MVC 2 web models
Development and maintenance of Web application is still a complex and
error-prone process. We need integrated techniques and tool support for
automated generation of Web systems and a ready prescription for easy
maintenance. The MDA approach proposes an architecture taking into account the
development and maintenance of large and complex software. In this paper, we
apply MDA approach for generating PSM from UML design to MVC 2Web
implementation. That is why we have developed two meta-models handling UML
class diagrams and MVC 2 Web applications, then we have to set up
transformation rules. These last are expressed in ATL language. To specify the
transformation rules (especially CRUD methods) we used a UML profiles. To
clearly illustrate the result generated by this transformation, we converted
the XMI file generated in an EMF (Eclipse Modeling Framework) model.Comment: International Journal of Computer Science & Information

Pattern Reification as the Basis for Description-Driven Systems
One of the main factors driving object-oriented software development for
information systems is the requirement for systems to be tolerant to change. To
address this issue in designing systems, this paper proposes a pattern-based,
object-oriented, description-driven system (DDS) architecture as an extension
to the standard UML four-layer meta-model. A DDS architecture is proposed in
which aspects of both static and dynamic systems behavior can be captured via
descriptive models and meta-models. The proposed architecture embodies four
main elements - firstly, the adoption of a multi-layered meta-modeling
architecture and reflective meta-level architecture, secondly the
identification of four data modeling relationships that can be made explicit
such that they can be modified dynamically, thirdly the identification of five
design patterns which have emerged from practice and have proved essential in
providing reusable building blocks for data management, and fourthly the
encoding of the structural properties of the five design patterns by means of
one fundamental pattern, the Graph pattern. A practical example of this
philosophy, the CRISTAL project, is used to demonstrate the use of
description-driven data objects to handle system evolution.Comment: 20 pages, 10 figure
