QVT ist ein Sprachkonzept der Object Management Group zur Transformation von formalen Modellen. In diesem Beitrag werden ausgehend von einem einfachen Fachklassenmodell die zentralen Konzepte und Techniken der Transformationssprache Operational Mappings vorgestellt, so dass abschließend eine vollständige Transformation eines UML-Modells der PIM-Ebene in eins der PSM-Ebene vorgenommen werden kan...

Many model-based approaches for user interface design start from a task model, for which the ConcurTaskTrees notation is frequently used. Despite this popularity and the importance that has been given to a close relation with UML, no relation has been established with UML state machines, which have been shown to be useful for the description of the behavior of user interfaces. This paper propos...

Despite its origins in software modeling, there has been growing interest in using the Unified Modeling Language (UML) for conceptual modeling of application domains. However, the UML has many constructs that are purely software oriented. Consequently, the suitability of the UML for modeling “real world” phenomena has been questioned. This research aims to assign real-world semantics to a core ...

The Unified Modelling Language (UML) is a diagrammatic notation widely used in the computing industry and often taught in universities as a way to represent software requirements specifications and design descriptions. In this paper we identify a number of problems associated with teaching UML and how we have minimised their impact by making use of the Executable/Translatable UML ( T UML). We d...

The Uni ed Modeling Language UML is a language for spec ifying visualizing and documenting object oriented systems UML com bines the concepts of OOA OOD OMT and OOSE and is intended as a standard in the domain of object oriented analysis and design Due to the missing formal mathematical foundation of UML the syntax and the semantics of a number of UML constructs are not precisely de ned This pa...

The integration of schedulability analysis with the industry standard Unified Modeling Language (UML) allows real-time developers to detect, at an early stage of development, unfeasible (unschedulable) real-time architectures. It, thus, prevents costly design mistakes and accelerates development schedules. This integration, accomplished through the timing extensions of UML, also allows the deve...

UML is being increasing used for the analysis and design of Web Information Systems. At the same time, many XML–based languages are cornerstones in the development of this kind of system. As a consequence of the predominance of these languages, there are many works in the literature devoted to exploring the relationships between UML and XML. In this paper we present a survey of current approach...

In this paper we present an approach that allows to validate properties of UML models. The approach is based on an integrated semantics for central parts of the UML. We formally cover UML use case, class, object, statechart, collaboration, and sequence diagrams. Additionally full OCL is supported in the common UML fashion. Our semantics is based on the translation of a UML model into a graph tr...

UML now has become one of the important tools in software system modeling and implementation. Database is generally an interim part of most system. UML is every aspect of software engineering can be modeled. This covers requirement management, project analysis, database design, deployment phase and maintenance. It Provides standard for software development. Reducing of costs to develop diagrams...
