Implemeting a component-based tool for interactive synthesis of UML statechart diagrams

The Unified Modeling Language (UML) has an indisputable role in objectoriented software development. It provides several diagram types viewing a system from different perspectives. Currently available systems have relatively modest tool support for comparing, merging, synthesizing, and slicing UML diagrams based on their semantical relationships. Minimally Adequate Synthesizer (MAS) is a tool that synthesizes UML statechart diagrams from sequence diagrams in an interactive manner. It follows Angluin's framework of minimally adequate teacher to infer the desired statechart diagram with the help of membership and equivalence queries. MAS can also synthesize sequence diagrams into an edited or manually constructed statechart diagram. In this paper we discuss problems related to a practical implementation of MAS and its integration with two existing tools (Nokia TED and Rational Rose) supporting UML-based modeling. We also discuss information exchange techniques that could be used to allow the usage of other CASE tools supporting UML

UML diagram synthesis techniques: a systematic mapping study

Context: The Unified Modeling Language (UML), with its 14 different diagram types, is the de-facto standard modeling language for object-oriented modeling and documentation. Since the various UML diagrams describe different aspects of one, and only one, software under development, they are not independent but strongly depend on each ot her in many ways. In other words, diagrams must remain consistent. Dependencies between diagrams can become so intricate that it is sometimes even possible to synthesize one diagram on the basis of others. Support for synthesizing one UML diagram from other diagrams can provide the designer with significant help, thus speeding up the design process, decreasing the risk of errors, and guaranteeing consistency among the diagrams. Objective: The aim of this article is to provide a comprehensive summary of UML synthesis techniques as they have been described in literature to date in order to obtain an extensive and detailed overview of the current research in this area. Method: We have performed a Systematic Mapping Study by following well-known guide-lines. We selected ten primary studies by means of a

Fujaba days 2009 : proceedings of the 7th international Fujaba days, Eindhoven University of Technology, the Netherlands, November 16-17, 2009

Fujaba is an Open Source UML CASE tool project started at the software engineering group of Paderborn University in 1997. In 2002 Fujaba has been redesigned and became the Fujaba Tool Suite with a plug-in architecture allowing developers to add functionality easily while retaining full control over their contributions. Multiple Application Domains Fujaba followed the model-driven development philosophy right from its beginning in 1997. At the early days, Fujaba had a special focus on code generation from UML diagrams resulting in a visual programming language with a special emphasis on object structure manipulating rules. Today, at least six rather independent tool versions are under development in Paderborn, Kassel, and Darmstadt for supporting (1) reengineering, (2) embedded real-time systems, (3) education, (4) specification of distributed control systems, (5) integration with the ECLIPSE platform, and (6) MOF-based integration of system (re-) engineering tools. International Community According to our knowledge, quite a number of research groups have also chosen Fujaba as a platform for UML and MDA related research activities. In addition, quite a number of Fujaba users send requests for more functionality and extensions. Therefore, the 7th International Fujaba Days aimed at bringing together Fujaba developers and Fujaba users from all over the world to present their ideas and projects and to discuss them with each other and with the Fujaba core development team

Rapid Modeling, Prototyping, and Generation of Digital Libraries- A Theory-Based Approach

Despite some development in the area of DL architectures and systems, there is still little support for the complete life cycle of DL development, including requirements gathering, conceptual modeling, rapid prototyping, and code generation and reuse. Even when partially supported, those activities are uncorrelated within the current systems, which can lead to inconsistencies and incompleteness. Moreover, the current few existing approaches are not supported by comprehensive and formal foundations and theories, which brings problems of interoperability and makes it extremely difficult to adapt and tailor systems to specific societal preferences and needs of the target community. In this paper, having the 5S formal theoretical framework as support, we present an architecture and a family of tools that allow rapid modeling, prototyping, and generation of digital libraries. 5S stands for Streams, Structures, Spaces, Scenarios, and Societies and is our formal theory for DLs. 5SL is a domain-specific, declarative language for DL conceptual modeling. 5SGraph is a visual modeling tool that helps designers to model a digital library without knowing the theoretical foundations and the syntactical details of 5SL. Furthermore, 5SGraph maintains semantic constraints specified by a 5S metamodel and enforces these constraints over the instance model to ensure semantic consistency and correctness. 5SGraph also enables component reuse to reduce the time and efforts of designers. 5SLGen is a DL generation tool that takes specifications in 5SL and a set of component pools and generates portions of a running DL system. The outputs of 5SLGen include user interface prototypes, in a generic UI markup language, for validation of services behavior and workflow representations of the running system, generated to support the desired scenarios

Assessment System for Assessing Knowledge Sharing Among Subject Experts in Secondary School

During the epoch of knowledge-based economy and knowledge management, teachers must learn in order to improve professional development. The success of knowledge management initiatives depends on knowledge sharing. The sharing of teaching-related knowledge may help teachers solve a variety of problems that they face, and the appropriate use of online knowledge-sharing activities is expected to assist teachers' knowledge sharing. Since studies related to educational knowledge sharing are rare, knowledge sharing behavior may be different between organization types. In order to promote knowledge sharing among subject experts within educational groups in secondary school; this study was implemented electronic assessment system to evaluate a knowledge sharing among teachers, which is helpful school organization's to develop knowledge and cultures
