- Which one is FALSE about models during software development? A Models improve the communication between client and developer. B A model is an abstraction. C Transforming an object model into source code is called model transformation. D System model contains three models: functional model, object model, and dynamic model. E Models are used to deal with complexity.Under what circumstances is it not required to deconstruct a general design into concerns of specific user views, and vice versa?The extra work and code required to prevent classes from being connected needlessly in object-oriented programming begs the question: why? Please provide the three most important reasons that support your stance.
- Why does avoiding classes that are needlessly connected require more work and writing of code in object-oriented programming? What are your position's three primary justifications?When appropriate, object-oriented design should be used. There are scenarios when a structured approach might be preferable. Is there any way to explain this, etc.Consider the process of searching for a book, to draw a sequence diagram based on thefollowing interactions:• The process started when a student object (this will be an actor) select search for abook operation with author id as parameter from the search page object.• The search page object validates the search criteria with itself.o If the author specified:• Search page object will run search by author operation on the catalog object.• The catalog object creates a search result object to form the result of the search.• The search result object creates and runs display the result operation on thesearch result page object.• The search result object replays a message “done” to the search object whichsends a reply message to the student object.• The student object views the results and closes the search result page object.• The search result page object closes the search result object.o If the author not specified, the search page object will repay the student object withan error message.•…
- Question: Scenario: You intend to develop an online voting system for general elections. The major use cases of the voting model system include authorizing User that includes simple users and the system's staff. The system manages election districts and election units. The election unit is the system counterpart of the “election center”. In the conceptual model, the election center is central to the election procedure, as it is the fundamental tallying point. The votes are casted using machines provided by the state and are places at the election center. The fundamental assumption of this system is that almost all citizens above a certain age should be able to participate in the election procedure. It is practically infeasible for election staff to manually enter all electors into the system. The system should thus be able to import an electronic list of electors. This system also manages different political parties and their respective candidates participating in the election…The most significant aspect of implementation development is the creation and adherence to the interface. The procedure may be summarised as follows:1. Create an interface. The interface specifies the external characteristics that are shared by all implementations.2. A simplified implementation. The abstract implementation defines the internal features that are shared by all implementations.3. The abstract class's extension. Each implementation recommends a distinct way to developing code that extends the abstract implementation and fulfils the interface's needed parts.when class A has an association relationship with class B, we implement this relationship in * :class A as Local variable O Data field O Method O Inheritance O
- The extra work and code required to prevent classes from being connected needlessly in object-oriented programming begs the question: why? Please provide the three most important reasons that support your stance.Draw and explain the use-case diagram, activity diagram, interaction diagram for the following: Consider developing a desktop-based framework to assist people in preparing for a certification exam like "SE@exam". A user can ask the system to create a quiz for them. The machine selects a group of questions from its database and assembles them into a quiz. It assigns a score to the user's responses and provides hints if the user needs them. We have helpers that give hints in addition to users. And also examiners who must certify questions to make sure they are not too trivial. Work out some of your use cases since we don't have real stake holders here, you are free to fill in details you think is required for this example.For the given design, Which of the following is NOT true about the design? Select one: a. It supports modular design. b. The AuthenticateUser sequence diagram can be reused only after a doB message call. c. The AuthenticateUser sequence diagram can be reused only when the authenticate() message is invoked on a B object. d. The DoFoo sequence diagram can be reused in any context where a B object and a C object are involved. e. The doB message must be called after the doA message.
