Systems, Views and Models of UML

In this paper we show by using the example of UML, how a software engineering method can benefit from an integrative mathematical foundation. The mathematical foundation is given by a mathematical system model. This model provides the basis both for integrating the various description techniques of UML and for implementing methodical support. After describing the basic concepts of the system model, we give a short overview of the UML description techniques. Then we show how they fit into the system model framework and sketch an approach to structure the UML development process such that it provides methodological guidance for developers.

Exemplary and Complete Object Interaction Descriptions

In this paper we present a variant of message sequence diagrams called EETs Extended Event Traces We provide the graphical notation discuss the methodological use of EETs to describe behavior of object oriented business information systems and sketch their semantics Special emphasis is put on the different implications of using EETs for exemplary and complete interaction descriptions. The possibility to describe interactions between single objects as well as composite objects with EETs makes them particularly suitable to describe the behavior of large systems.

Towards a Formalization of the Unified Modeling Language

The Unified Modeling Language UML is a language for specifying visualizing and documenting object oriented systems UML combines the concepts of OOA OODOMT 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 defined.This paper outlines a proposal for the formal foundation of UML that is based on a mathematical system model

Towards a Precise Semantics for Object-Oriented Modeling Techniques

In this paper we present a possible way how a precise semantics of object oriented modeling techniques can be achieved and what the possible benefits are .We outline the main modeling techniques used in the SysLab project sketch how a precise semantics can be given and how this semantics can be used during the development process.
