Design patterns are solutions to common problems that developers faced during software development. In this study, we analysis Design Patterns by using Rhapsody in Java. We show how Java language features affect the implementation of Design Patterns using Rhapsody, analysis some potential Java programming patterns, and demonstration of how studying design patterns can contribute to provide the reusable solution to a commonly occurring problem within a given idea in software design. Keywords: Design Patterns, Java, Rational Rhapsody, Object-Oriented. 1. INTRODUCTION s we developed more complex computer systems, we are going to face difficulties in construction rather A than difficulties in analysis. The difficulties in developments are solved by designing programming solutions for such difficulty in the context of the software application we are trying to develop . Some constructional problems occur over and over again across a wide range of different Software. Obviously, we can design a common solution to such repeating problems, and then try to adjust such a common solution to the specific need of the software we are currently building. Such common solutions are usually referred to as design patterns. Design Patterns are very popular among software developers.

  • Interpretation Problems in Code Generation from UML State Machines - a Comparative Study
    Interpretation Problems in Code Generation from UML State Machines - a Comparative Study Anna Derezi ńska, Marian Szczykulski Institute of Computer Science, Warsaw University of Technology, Nowowiejska 15/19, 00-665 Warsaw, Poland A.Derezinska @ii.pw.edu.pl Abstract. A practical utilisation of a model-driven approach to an information system development is hampered by inconsistencies causing interpretation problems. This paper focuses on the state machine that is a common means for modelling behaviour. A transformation of classes with their state machines into a code assists in the efficient development of reliable applications. A set of interpretation problems of state machines was revisited in accordance with the UML specification and examined on model examples transformed to an executable code. The paper compares the implementation of the problems regarding to two tools that support the transformation and takes into account the most comprehensive set of the UML behavioural state machine concepts. The tools are the IBM Rational Rhapsody, which transforms state machines to C, C++, Java, Ada and the Framework for eXecutable UML (FXU) dealing with the C# code. The basic information about the FXU tool is also given. Keywords: UML state machines, statecharts, semantic variation points, UML model to code transformation 1 Introduction The Unified Modelling Language (UML) is a notation commonly used in different phases of an information system development. UML models can be employed to describe static and dynamic aspects of a system from different viewpoints. They constitute a basis for Model Driven Engineering (MDE) [1], where model transformations are used for system development and verification. Building applications based not only on structural models, like class diagrams, but also on behavioural models is considered to be an issue of a sheer practical importance.

This capstone report provides an overview of the main MDE concepts with a focus on Unified Modeling Language (UML). It provides an overview of various model transformation tools, and selects three from the group for further evaluation. The findings of this report confirm that MOLA and BOTL are still in the developmental stages and do not satisfy identified ideal requirements of a robust model transformation tool.
