First, in order to prepare a reimbursement request, they have to do the following activities at the same time: gather all of the receipts the university requires for reimbursement and complete the official reimbursement form. They then submit both the receipts and the form to their departmental secretary for checking purpose. If something on the form is incorrect, the secretary returns the form to the employee and ask for correction. If the form is correct, the employee is asked to review the reimbursement amounts, which are determined by an analysis of the reimbursement request. If the amount shown is not correct, the employee must indicate that this is the case. If the amount shown is correct, then the employee": responsibilities for reimbursement are complete.
- use java and javaFX A simple Library Management System aims at developing a computerized system to maintain all the day-to-day activity of a library. This functional project handles data of books and their copies, users that can be either students or teachers as well as book loans, Each book has an id, title, publisher, author, year, number of copies, copies of the book, financial value and status(true if at least one copy is available). Each copy has id, status whether a copy is available to be borrowed of not and insert date. A user has id, first name, last name, password and registration date. In addition to the total fine which is the total of each fine the user get for every late return of a book. Students has major whereas staff has department. When borrowing a book, the system recording the copy of the book being issued (borrowed), the borrower and the date at which borrowed.

Busy Bees Home Cleaning Service employs a number of cleaners that take cleaning jobs from a central dispatch service. Customers can request a cleaning job by phoning in and making an appointment. The employee that takes the call checks if there is sufficient staff for the appointment. If there is, the employee records the customer and appointment. If there isn’t the staff member suggests other times that are available. Customers can also request a regular cleaning service (e.g. weekly), as well as a specific cleaner. If there is any variation in the job (e.g. the customer requests that windows be cleaned in addition to the normal cleaning job) the cleaner informs the office before the bill is credited to the customer’s account. Most customers are charged via their credit card; regular customers can have an account whereby they are invoiced on…Question 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.
