In the paper practical issues concerning the use of UML as a knowledge representation method for rules are discussed. A proposal of an UML-based representation for the XTT structured representation for rules is presented. Since some deep semantical di erences between UML and rule-based representation exist, several possible UML representations are evaluated. A practical algorithm for building a...

This position paper takes a bottom-up approach that analyzes the suitability of UML for modeling aspect-oriented software, and compares it with the UML support for modeling object-oriented software. We first introduce the basic concepts of AspectJ, a state-of-the-art aspect-oriented programming language, and then take a naïve approach using standard UML, as it is, for modeling these concepts. A...

The paper presents the essential features of a new member of the UML language family that supports working with object-oriented frameworks. This UML extension, called UML-F, allows the explicit representation of framework variation points. The paper discusses some of the relevant aspects of UML-F, which is based on standard UML extension mechanisms. A case study shows how it can be used to assi...

The UML Testing Profile provides support for UML based model-driven testing. This paper introduces a methodology of how to use the testing profile in order to modify and extend an existing UML design model for test issues. As a case study, a new roaming algorithm for bluetooth devices has been develped at the University of Lübeck, is modelled using UML. The usability of the UML Testing Profile ...

UML-B provides a graphical front end for Event-B. It adds support for class-oriented and state machine modelling. UML-B is similar to UML but has its own meta-model. UML-B provides tool support, including drawing tools and a translator to generate Event-B models. The tools are closely integrated with the Event-B tools. When a drawing is saved the translator automatically generates the correspon...

Alloy is a new modeling language for software design, while Unified Modeling Language (UML) is a standard modeling language widely used in industry. This paper analyzes the similarities and the differences between Alloy and UML. It focuses on the complexity differences, accuracy differences, and the expression differences between these two languages. Both Alloy and UML can be used to specify th...

Giving a formal semantic to an UML Activity diagram (UML AD) is a hard task. The reason of this difficulty is the ambiguity and the absence of a precise formal semantic of such semi-formal formalism. A variety of semantics exist in the literature having tackled the aspects covered by this language. We can give as example denotational, functional and compositional semantics. To cope with the rec...

The advent of multi-core processors offers an opportunity to increase the usage of Executable UML. Researchers are advocating the division of software systems into a productivity layer and an efficiency layer to shield mainstream programmers from the complexities of parallelism. Such separation of application and platform concerns is the foundation of Executable UML. To leverage this opportunit...

The process of modeling and developing of real-time and embedded systems should be supported by suitable methods and notations. In the paper we examine different approaches for customizing standard modeling language UML to model such systems in object-oriented analysis and design. We propose the use of UML standard lightweight extensibility mechanisms (stereotypes) without changing the UML meta...
