Overview<\/h2>\n

A major engineering problem today is the predictable development of reliable software-intensive systems. The object-oriented paradigm is an important part of such development.<\/p>\n

Object-oriented methods can be divided into languages<\/em>, distribution<\/em>, and analysis and design<\/em>. There change in the language<\/em> category, particularly Java and C#. Distribution<\/em> includes the use of vendor libraries of classes and also distributed objects as specified by the Object Management Group etc.\u00a0 Basic to the entire enterprise, however, are analysis and design<\/em>, which has remained remarkable stable for years. Object-Oriented Analysis and Design <\/em>includes the overall goals of the object paradigm, the selection of classes, the relationships among them, and their utilization to implement systems.<\/p>\n

Required Background<\/h2>\n

A knowledge of C++ or Java (MET CS 565) and software engineering methods (MET CS 673) are required.\u00a0\u00a0 It is preferable to have taken Design Patterns (MET CS 665).<\/p>\n

Materials and references<\/h2>\n

The recommended textbook is “Applying UML and Patterns: An Introduction to Object-Oriented Analysis and Design, and the Unified Process ” by Larman (Prentice Hall) 2nd edition, Published July 2001, 627 pages, ISBN 0130925691.\u00a0 This is the first time that this instructor has used this book, and it is not clear how much the book will be used.<\/p>\n

The instructor will provide notes for all classes.<\/p>\n

    Learning Objectives<\/h2>\n

    Students will be able to …<\/p>\n

      \n
    • … analyze problems from an object perspective<\/li>\n

      Grading<\/h2>\n

      The course will consist of homework and a project, weighted as follows:<\/p>\n

      1.\u00a0\u00a0\u00a0\u00a0\u00a0 Homework:\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0 30%<\/p>\n

      There are three phases for the project, graded as follows:<\/p>\n

        \n
      • phase 1 (problem statement): \u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0 1\/9<\/li>\n
      • phase 2 (analysis): \u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0 2\/9<\/li>\n
      • phase 3 (design): \u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0 1\/3<\/li>\n
      • phase 4 (implementation and critical review): 1\/3<\/li>\n<\/ul>\n

        Parts are evaluated equally unless otherwise stated.<\/p>\n

        Late homework is not accepted unless there is a reason why it was impossible<\/em> for you. If there is such an impossibility, the work will be graded on a pass\/fail basis.<\/p>\n

        Project Organization<\/h2>\n

        You will be required to submit an analyzed, designed and implemented project according to the deadlines shown in the schedule. Detailed requirements will follow.<\/p>\n

        With the instructor\u2019s permission, it may be possible to substitute all or part of the project with an investigation of tools for OOA&D such as Rational Rose or Together.\u00a0 This will require a detailed evaluation and an investigation of how these tools are being used extensively in a particular company.<\/p>\n

        Teams two are permitted, and will be evaluated at a higher standard. All members must know all parts.<\/p>\n

        You will be required to give a presentation on at least two of the phases in your project.<\/p>\n

        Syllabus:<\/h2>\n

        This syllabus is subject to about 15% modification.<\/p>\n

        The order of topics will be driven by the notes, which the instructor will hand out, not by the textbook. The textbook will serve as background and reference.<\/p>\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n

          Draw a class model for an application for drawing human figures.\u00a0 The picture shown is a typical product of the application.\u00a0 The figures are always<\/em> neck-upward; mouths are always<\/em> lines, necks always<\/em> rectangles, etc. \u2013 the shapes that appear in the figure.\u00a0 Assume that the business will never change — but we want to be able to easily upgrade the shop\u2019s capability within these constraints (e.g., draw necks with various colors, new kinds of border lines).\u00a0 The class model should make figure drawing convenient (e.g., allowing the retrieval of previously constructed figure parts). Show attributes or operations whenever they clarify your solution.\u00a0 Include useful abstractions (but to extend the current business).<\/p>\n

          There is no requirement to take into account the GUI for the application (icons, menu\u2019s etc.)<\/p>\n

          Here is a scenario: <\/strong><\/strong><\/p>\n

          <\/strong> The user … pulls onto the monitor \u201cabeLincolnFace14\u201d (which excludes the ears and neck) <\/strong><\/span><\/strong><\/strong><\/p>\n

          <\/span><\/strong><\/strong> … adds \u201cear123\u201d on the left by dragging to its vicinity and releasing <\/strong><\/span><\/strong><\/strong><\/p>\n

          <\/strong><\/span><\/strong><\/strong> The application places ear123 in a correct position<\/strong><\/span><\/strong><\/strong><\/span><\/strong><\/strong><\/p>\n

          <\/span><\/strong><\/strong><\/span><\/strong><\/strong> The user invokes the \u201ccomplete with suitable parts\u201d command.<\/strong><\/span><\/strong><\/span><\/strong><\/strong><\/span><\/strong><\/strong><\/p>\n

          <\/span><\/strong><\/span><\/strong><\/strong><\/span><\/strong><\/strong> The application <\/strong><\/span><\/strong><\/span><\/strong><\/span><\/strong><\/strong><\/span><\/strong><\/strong><\/p>\n

          <\/span><\/strong><\/span><\/strong><\/span><\/strong><\/strong><\/span><\/strong><\/strong> \u2026 completes the figure with a neck and hat that it considers most suitable. <\/strong><\/span><\/strong><\/span><\/strong><\/span><\/strong><\/strong><\/span><\/strong><\/strong><\/p>\n

          2. Be specific about associations: Do you mean two-way aggregations?<\/em><\/em><\/em><\/em><\/p>\n

          3. You have introduced a class whose name does not indicate a clear purpose and which is not a domain class.\u00a0 Explain it\u2019s purpose.<\/em><\/em><\/em><\/em><\/p>\n
