Conceptual Modeling for Advanced Application Domains

In this paper a joint topology-geometry model is proposed for dealing with multiple representations and topology management to support map generalization. This model offers a solution for efficiently managing both geometry and topology during the map generalization process. Both geometry-oriented generalization techniques and topology-oriented techniques are integrated within this model. Furthermore, by encoding vertical links in this model, the joint topology-geometry model provides support for hierarchical navigation and browsing across the different levels as well as for the proper reconstruction of maps at intermediate levels.

Data abstractions for database systems

Data abstractions were originally conceived as a specification tool in programming. They also appear to be useful for exploring and explaining the capabilities and shortcomings of the data definition and manipulation facilities of present-day database systems. Moreover they may lead to new approaches to the design of these facilities. In the first section the paper introduces an axiomatic method for specifying data abstractions and, on that basis, gives precise meaning to familiar notions such as data model, data type, and database schema. In a second step the various possibilities for specifying data types within a given data model are examined and illustrated. It is shown that data types prescribe the individual operations that are allowed within a database. Finally, some additions to the method are discussed which permit the formulation of interrelationships between arbitrary operations.

From textual scenarios to a conceptual schema

Scenarios are a very popular means for describing and analyzing behavioral aspects on the level of natural language. In information systems design, they form the basis for a subsequent step of conceptual dynamic modeling. To enhance this step, linguistic instruments prove applicable for transforming scenarios into conceptual schemas of various models. This transformation usually consists of three steps: linguistic analysis, component mapping and schema construction. Within this paper we investigate to which extent these steps may be performed automatically in the framework of KCPM, a conceptual predesign model which is used as an Interlingua between natural language and arbitrary conceptual models.

Linguistically based requirements engineering — the NIBA-project

Abstract Usually, the development of an information system (or some part of it) starts with requirement elicitation followed by a phase of collecting and analyzing which results in a set of requirements specifications. As opposed to conventional conceptual modeling, where input texts are formalized, our approach suggests the idea of collecting and cataloguing natural language patterns in a non-textual form immediately after a linguistic analysis. This linguistic analysis is done according to the NTMS model. Collecting and cataloguing of natural language data is supported by KCPM.

Business Process Modeling and Requirements Modeling

Business process modeling is an important part of each software development project. No software is developed without specifying its use within the context of business processes. Since business process modeling is an important task during requirements engineering, in our opinion the same basic modeling notions should be used. This paper gives a first proposal how this can be done.

A characterization of OOA tools

Despite unification of tools supporting object oriented analysis (OOA) there is still a variety of tools making it hard to select one of them for a given environment. Clearly, if one is willing to apply a certain favorite OOA method, the choice would be restricted to tools supporting that method. However, there are usually several such tools and no clear criteria for selecting between them without extensive experimentation. But this, in general, is impossible due to time restrictions. The paper deals with the selection problem and poses a set of OOA tool characteristics that can be used for tool description and thus form a base for an efficient tool comparison. In order to show how this set of characteristics may be applied, we give, as an example, a characterization of OMTool.

Modellierung in der Softwaretechnik: eine Bestandsaufnahme

ZusammenfassungDie Fähigkeit zur Modellbildung gehört zu den grundlegenden kognitiven Leistungen des Menschen. Modelle werden (als Nachbilder) zum Zwecke der Erkenntnis, aber auch (als Vorbilder) für die Konstruktion neuer Artefakte genutzt. Damit ist die Modellierung Grundbestandteil von Natur- und Ingenieurwissenschaften, der Mathematik und vor allem auch der Informatik. Hier liegen ihre Ursprünge in der mathematischen Logik, der Automatentheorie und der Schemaentwicklung für Datenbanken. In der Softwaretechnik wurde sie vor allem durch Peter Chens Entity/Relationship-Modell populär. Seit dem Einzug der Objektorientierung in den frühen 1990er-Jahren hat sich die Modellierung auch hier zu einem eigenständigen und dynamischen Teilgebiet entwickelt. Zusammen mit der raschen Verbreitung der Unified Modelling Language (UML) haben heute die Ansätze der modellgetriebenen Software-Entwicklung und -architektur (MDD/MDA) die Modellierung in den Mittelpunkt des Software-Entwicklungsprozesses gerückt.Dieser Übersichtsartikel beleuchtet zunächst die Ursprünge, wichtige Begriffe und Unterscheidungen von Modellen in der Softwaretechnik. Die darauf folgende Betrachtung von Modellen als Zeichen eröffnet einen semiotischen Zugang zur Modellierung. Nach der Erläuterung einiger wichtiger Modellierungskonzepte und -konstrukte werden am Schluss verwandte Begriffe wie Metamodelle und Ontologien sowie die Einbindung der Modellierung in den Software-Entwicklungsprozess behandelt.
