More About Object Oriented Analysis and Design using UML Notes

The Designing Software for applications which are large in size is usually a very complicated work. it is complex and thereby arguably be said that there is no limit to how complex a software design could get. This is because, we usually design software with the motive to model real-world phenomenon. This is a course that strongly helps students build a foundation of understanding and designs of a modern computing system. In this course, techniques that go into designing a modern microprocessor will be explored. Further, a fundamental understanding of the architecture of computer will be made possible, and this is going to help students in understanding design processors and hardware and also builds a foundation in knowing more about compilers, operating systems, as well as high-performing programming.

Results of studying OOAD –

  • This will help a student find solutions of complex problems using object-oriented approach.
  • A student after studying OOAD will be able to represent classes, responsibilities and states using the notations of UML.
  • This will also support a student in the process of identifying classes, responsibilities of the problem domain.

Important Questions in Object Oriented Analysis and Design –

  • Prepare an object diagram showing at least 10 relationships among the following object classes. Include associations and qualified associations, aggregations, generalizations, and multiplicity. You may add additional objects. Also, show attributes and operations. School, playground, principal, school board, classroom, book, student, teacher, canteen, restroom, computer, desk, chair.
  • What the use is of “include” and “extends” relationships in the use-case diagram?
  • What is an abstract class? Mention its use. Can the concrete class be a superclass? If yes, give an example, if no, give a reason.
  • Create a class hierarchy to organize the following drink classes: Mineral water, wine, alcoholic, nonalcoholic, grape juice, soda, bears.
  • What do you mean by Software Development Life Cycle (SDLC)? What are the phases (stages) of it? Which phase requires maximum efforts? Also explain why domain analysis i.e. domain class model, domain state model, and domain interaction model is important.
  • Under what situation activity diagram should not be used? Which diagrams are preferable under such situations?
    Also give practical situations, when to use the following diagram: a. Use-Case Diagram, b. Object Diagram, c. Interaction diagram
  • What are the similarities/dissimilarities between a sequence diagram and a collaboration diagram? Draw the Interaction diagram for an ATM – used for a card-based banking system.
  • Draw the use-case diagram for Hotel Information System. There are two types of customers: Tour-group customers and Individual customers. Both can book, cancel, check-in and check-out of a room by Phone or via the Internet. There are booking process clerk and reception staff who manages
    it. A customer can pay his bill by credit card or pay utility bills.
