- KonferenzbeitragAn Approach to use Executable Models for Testing(Enterprise modelling and information systems architectures – concepts and applications, 2007) Soden, Michael; Eichler, HajoThis paper outlines an approach to test programs by transforming them into executable models. Based on OMG’s metamodelling framework MOF in combination with an action language extension for the definition of operational semantics, we use QVT to transform abstract syntax trees as code representations into executable models. We argue that these models provide an adequate abstraction for simulation and testing, since platform dependencies can be resolved in a controlled way during transformation to detach the program logic from its environment. A prototypic implementation based on eclipse EMF underpins the approach.
- KonferenzbeitragArchitecture principles – A regulative perspective on enterprise architecture(Enterprise modelling and information systems architectures – concepts and applications, 2007) Bommel, Patrick van; Buitenhuis, Pieter; Hoppenbrouwers, Stijn; Proper, ErikIncreasingly, organizations make use of enterprise architectures to direct the development of the enterprise as a whole and its IT portfolio in particular. In this paper we investigate the regulative nature of enterprise architecture. We aim to develop a fundamental understanding of the regulative needs that underly an enterprise architecture, and then take these needs as a starting point to arrive at requirements on the language (architecture principles) used to denote enterprise architectures. We furthermore discuss the process of formulating principles as well as their semantics.
- KonferenzbeitragBPMN-Q: A Language to Query Business Processes(Enterprise modelling and information systems architectures – concepts and applications, 2007) Awad, AhmedWith the growing role business processes play in today’s business life, they are being seen as an asset for the organization. With hundreds of process models developed by different process designers it would be helpful to look up the repository for models that could handle a similar situation before developing new ones. In this paper we introduce a new visual query language for business processes. The language addresses processes definitions. It extends BPMN for its abstract syntax as BPMN is a standard visual notation for modeling business processes. The overall architecture of the system in which the language can fit, in addition to the details of the query processing are also discussed.
- KonferenzbeitragDesign and Usage of an IT-System for workplace management with ergonomic analysis under health protection aspects(Enterprise modelling and information systems architectures – concepts and applications, 2007) Dubian, Clemens; May, WolfgangThis article describes an information system for analysis and description of workplaces under the aspects of health protection and ergonomic risks, which is currently being developed at Volkswagenwerk Kassel. The system provides an instrument for matching ergonomic risks of workplaces with work limitations of employees for an efficient assignment of employees to appropriate workplaces. It integrates data from several existing systems and collects additional data. The collection and maintenance of data is accomplished by an analysis team and by the team leaders in the factory. Besides the functional aspects, the following two issues have been solved: minimizing the effort for the collection and maintenance of data by using a hierarchical categorization of the objects of interest and their properties. Secondly, for accomplishing the acceptance and direct benefit for the following user groups (health care, human resource management, and most of all, local supervisors), group-specific graphical user interfaces are provided.
- KonferenzbeitragEA Model as central part of the transformation into a more flexible and powerful organisation(Enterprise modelling and information systems architectures – concepts and applications, 2007) Gerber, Stefan; Meyer, Uwe; Richert, ClausThis report introduces an approach how Enterprise Architecture (EA) design can be deployed in a large financial organisation for strategic transformation. Our EA design embraces all main components of the business organisations, its information systems and the way they work to achieve business objectives. In order to tackle such EA design and its deployment, governance, design and measurement principles are required to keep EA consistent and avoid misunderstandings among stakeholders. Since EA focuses on a holistic view of the organisation, full EA deployment is risky due to cost and organisational impact. Therefore we use an iterative approach within EA deployment that will be considered as an assessment process evaluating the whole IT-landscape of a certain CIO area. There are metrics used which allow the identification of transformation objects and these will be reworked in different structures by using architectural principles and then integrated into EA. Finally the existing EA will be evaluated (together with transformation object) by EA design principles and either the transformation will be rejected or design principles will be adopted. In order to make this model operative it is embedded in an architecture organizational structure which is independent from the organizational structure of the enterprise.

- KonferenzbeitragGenerating Visualizations of Enterprise Architectures using Model Transformations(Enterprise modelling and information systems architectures – concepts and applications, 2007) Buckl, Sabine; Ernst, Alexander M.; Lankes, Josef; Schweda, Christian M.; Wittenburg, AndréGiving account to the importance of enterprise architecture (EA) modeling, this article sketches common issues in visualization handling that we came across dur- ing an extensive survey of the existing tool support for EA management in 2005. We introduce the research project software cartography, in which we develop an approach for EA modeling including a method for the automatic creation of EA models and vi- sualizations. This approach is based on model transformations, which we use to link the data to be visualized and their graphical representation, thereby circumventing the error prone and time consuming task of manual creation of the visual models. A brief overview of a prototypic implementation of this approach complements the theoretic findings and illustrates applicability for visual modeling and documenting the EA.
- KonferenzbeitragModelling of Cross-Organizational Business Processes - Current Methods and Standards(Enterprise modelling and information systems architectures – concepts and applications, 2007) Ziemann, Jörg; Matheis, Thomas; Freiheit, JörnNot only since the upcoming of Service-oriented Architectures the modelling of cross-organizational business processes is a heavily investigated field comprising dozens of standards based on different concepts. New techniques on the implementation site, e.g. Web Service orchestration and choreography, further extended the possibilities and requirements on such standards. To systematically order and present a comprehensive state of the art of relevant methods and standards this paper first describes requirements that occur in cross-organizational business processes both for concepts and modelling languages. Then the most important state of the art concepts for modelling cross-organizational processes are described, followed by a list of selected modelling languages. Based on the requirements defined before, a selection of languages is analysed in greater detail.
- KonferenzbeitragOBSE – an approach to Ontology-based Software Engineering in the practice(Enterprise modelling and information systems architectures – concepts and applications, 2007) Bachmann, Andrej; Hesse, Wolfgang; Russ, Aaron; Kop, Christian; Mayr, Heinrich C.; Vöhringer, JürgenIn this article we present a new approach to Ontology-based Software Engineering (OBSE) meant for practical use in enterprises and industrial projects. Following this approach, Software projects are no longer driven only by requirements and models but also by one or several ontology/ies covering their application domain. Our main thesis says that OBSE can offer similar opportunities and benefits for re-engineering and re-use in the early phases of software development as object orientation does for the later ones. OBSE is to be supported by tools which integrate ontologies in the SE process. A prototype of such a tool – based on the KCPM and EOS methodologies – is presently being developed in a joint project of our groups.
