Short Questions for OOAD and Visual Modeling

  • ×

    Hidden Questions!

    Some short questions are not visible. Usually teachers hides their visibility if they are few in number. Subject Expert recommends them to have more than 70+ questions against the topic and make them public.

  • 1 What is the purpose of OO analysis and design?

    The purpose of OO analysis and design is Identifying the objects of a system. Identify their relationships. Make a design which can be converted to executables using OO languages.

  • 2 Name the industry known visual modeling methodologies emerged initially?

    Industry known visual modeling notations are:

    1. Booch 
    2. Object Modeling Technology (OMT)
    3. Unified Modeling Language UML 

  • 3 What are the benefits of iterative and evolutionary development?


    • Less project failure, better productivity, and lower defect rates. Shown by research into iterative and evolutionary methods
    • Early rather than late mitigation of high risks (technical, requirements, objectives, usability, and so forth)
    • Early visible progress
    • Early feedback, user engagement, and adaptation, leading to a refined system that more closely meets the real needs of the stakeholders
    • Managed complexity, the team is not overwhelmed by “analysis paralysis” or very long and complex steps
    • The learning within an iteration can be methodically used to improve the development process itself, iteration by iteration

  • 4 Why Unified Process (and most new methods) encourage a combination of risk-driven and client-driven iterative planning?


    Because they try to accomplish the following two goals:

    1. Identify and drive down the highest risks
    2. Build visible features that the client cares most about

  • 5 For complex, changing systems how feedback and adaptation help in their success?


    • Feedback from early development, programmers trying to read specifications, and client demos to refine the requirements.
    • Feedback from tests and developers to refine the design or models.
    • Feedback from the progress of the team tackling early features to refine the schedule and estimates.
    • Feedback from the client and marketplace to re-prioritize the features to tackle in the next iteration.

  • 6 Describe the life-cycle approach of iterative development.

    In this life-cycle approach, development is organized into a series of short, fixed-length (for example, three-week) mini-projects called iterations; the outcome of each is a tested, integrated, and executable partial system.

  • 7 Describe Test Driven Development (TDD)?


    Test-driven development (TDD) is a software development process that relies on the repetition of a very short development cycle, first the developer writes automated test case that defines a desired improvement or new function, then produces the minimum amount of code to pass those tests, and finally refactors the new code to acceptable standards.

  • 8 How we can apply Unified Modeling Language?


    • UML as sketch
      Incomplete diagrams with text
    • UML as blueprint
      Detailed design diagram to visualize and understand the code
      1. Forward Engineering: Design to code
      2. Reverse Engineering: Code to design synchronization
    • UML as Programming Language
      Implementation in a programming language

  • 9 What are the perspectives of UML?



    The diagrams are interpreted as describing things in a situation of real word or domain of interest.


    Diagrams describe the software abstraction or components with no commitment to particular implementation


    Diagrams describe software implementation in a particular technology.

  • 10 What are the basic Object Oriented Programming concepts?

    Following are the basics Object Oriented Programming concepts:

    • Encapsulation
    • Information Hiding
    • Inheritance
    • Polymorphism
