Mapping UML Techniques to Design Activities

چکیده
INTRODUCTION Over the years, the information system design process (Gero and Kazakov, 1996; Goldschmidt, 1997; Guindon, 1990; Jeffries et al., 1981; Parnas and Clements, 1986) has been investigated using a variety of perspectives. Researchers have examined cognitive aspects of design (Goldschmidt, 1997; Guindon, 1990; Guindon, Krasner, and Curtis, 1986; Rowe, 1987; Sen, 1997), design strategies (Adelson and Soloway, 1988; Batra and Antony, 1994; Guimaraes, 1985; Jeffries et al., 1981), and reuse tasks (Sen, 1997). A variety of modeling techniques, such as the entityrelationship model (Chen, 1976), data flow diagrams (Gane and Sarson, 1979), and object-oriented models (Booch, 1994) have also been developed to document the artifacts generated during the design process. Increasingly, the object-oriented design paradigm and related modeling techniques have been the choice of system designers. It is reasonable to expect that these modeling techniques (proposed to document the design products) will assist or at least not hinder the designer behaviors (that is, the process of IS artifact design). The expectation has, however, not been subjected to investigation. In this contribution, we focus on behaviors that designers exhibit during actual design sessions and investigate how these behaviors are supported by the de facto standard for object-oriented modeling, the Unified Modeling Language (UML) (Booch, Jacobson, and Rumbaugh, 1999). We focus on three core UML techniques: use cases, class diagrams, and sequence diagrams. To observe behaviors employed

Mapping Sequence diagram in Fuzzy UML to Fuzzy Petri Net
This ability in fuzzy UML, practically leaves the customers and market’s need without response in this important and vital area. Here, the available sequence diagrams in fuzzy UML will map into fuzzy Petri net. However, the formal models ability will be added to the Semi-formal fuzzy UML. This formalization will add the automatic processing ability to the Semi-formal fuzzy UML. Further more, t...
متن کاملAn Isomorphic Mapping for SpecC In UML
An isomorphic UML mapping of SpecC syntax and its semantic preserving transformation is presented. SpecC is one of several competing efforts to deal with the system-level specification and design of embedded systems, and for which we have formalized UML mappings, into what is collectively known as YES-UML. YES-UML is a broadspectrum notation built as a series of extensions to UML to support exi...

Mapping Activity Diagram to Petri Net: Application of Markov Theory for Analyzing Non-Functional Parameters
The quality of an architectural design of a software system has a great influence on achieving non-functional requirements of a system. A regular software development project is often influenced by non-functional factors such as the customers' expectations about the performance and reliability of the software as well as the reduction of underlying risks. The evaluation of non-functional paramet...
متن کاملSimplified Bi-Directional Transformation of UML Activities into Petri Nets
Model-to-Model mapping should offer the advantage of fully operational bi-directional mapping between different models or formalisms that share some common properties. However in reality this is not easily achievable. It is acknowledged that previous work was presented where it was shown how Triple Graph Grammars are useful to achieve the mapping. UML 2 activities share some similarities with P...
