Although while selection structures play a crucial role in programming, they are not perfect. Any program that deals with a large number of users, whether they are consumers, online clients, or any other kind of transaction, has to use the same iterative approach. Do those working in these fields adhere to a code of conduct? What makes these structures unique in comparison to others?
Let's imagine we develop a browser based training system to help people prepare for a certification exam.A user can request a quiz for the system.the system picks a set of questions from its database and composes them together to make a quiz.it rates the users answers and gives hints if the user requests it.
draw a use case diagram.
pick up two case(s) and write specification.
Develop a design class diagram and package diagram for a library system according to the given scenario.
The library system provides users with the opportunity to borrow books from the library. The system includes a service page that displays all services such as borrowing and computer services. It also includes a catalog where all possible books are categorized. Users can communicate with the library via the details available on the contact page.
The system allows only registered users to borrow books and the books are either hardcopy or e-books. To borrow a book the system will have to check for the eligibility of the user before approval. If the user is not eligible, then the request will be declined.
Borrowing could be done via the library system or in person. The admin is responsible for the in-person borrowing. For the borrowing of any book, a form that is available on the forms page has to be filled by the user. Also, the system must check for the availability of a book before…

- Despite their importance, selection structures cannot complete the job on their own. All of us have to deal with the circumstance of having to repeat a succession of statements for various customers or transactions, or for online clients, at some point. To what extent do these jobs need certain types of frameworks? In what way are they different?arrow_forwardEven if the processes you're trying to describe have nothing to do with system analysis, you may still give them a go to explain using structured English.arrow_forwardDraw 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.arrow_forward
- Programming cannot exist without the use of selection structures, however these structures are not without flaws. Because of the large number of users, online customers, and diverse types of transactions, each application must follow the same iterative method. Are those working in these fields required to comply by a certain code of ethics? What exactly is it that sets these constructions apart from others?arrow_forwardHow important is it to have a consistent user interface in the design of the SoS interface? When it comes to the cost-effectiveness of an all-in-one user interface, a lot of elements come into play. What do you mean by variables?arrow_forwardDraw the Level 0 and Level 1 Data Flow Diagram for a Car Purchasing System. Scenario: An owner has to register first to buy a car by providing his personal details, which are later saved in the registration database, then the system will give the registration number back to the owner. The owner will then need to provide the model, name, type of car he wants to buy, and the system automatically reads the status of the car from the car database, which later informs the owner regarding its availability. The owner pays the cost of the car. The system will update the payment database and issue a receipt back to the owner.arrow_forward
- Draw the preliminary class diagram for the system described in the following requirements (the cardinality of the relationships is optional). A company has decided to computerize the circulation of coordinating the documents around its offices, and to do this by installing a network of electronic desks system. Each electronic desk provides users with the following services: A blotting pad (provides a basic word processing facilities), which can hold a document that the user is currently working on. A filling cabinet, which allows a user to store documents. A mail service, which allows a user to communicate with other users on the network. Each electronic desk is provided with three trays, corresponding to IN, OUT and PENDING in traditional offices. to organize mail documents. The network will automatically put new mail into a user's IN tray and will periodically take documents from the OUT tray and mail them to their recipients. Documents can move between the trays and the blotting…arrow_forwardStructured English might be useful when dealing with procedures that don't include systems analysis. Additional details are provided below.arrow_forwardCreate a sample data flow diagram of a database: For example, a residents filling out the form (personal information) and an admin updating/accessing the records of the residents. (Name, address, contact #, family members).arrow_forward
- Despite the fact that the methods you are trying to describe have nothing to do with system analysis, you may attempt to explain them using structured English.arrow_forwardLook for methods to describe processes that aren't part of a systems analysis using Structured English, and how you may do so.arrow_forwardDraw the UML Class Diagram modeling the structure (classes,associations) of the new application for registration of a module(condition: attendant>80% and pass the required module).
