Example - University Registration System as a Running Example The UTD wants to computerize its registration system . The Registrar sets up the curriculum for a semester - One course may have multiple course offerings o Students select four (4) primary courses and two (2) alternate courses o Once a student registers for a semester, the billing system is notified so the student may be billed for the semester o Students may use the system to add/drop courses for a period of time after registration o Professors use the system to set their preferred course offerings and receive their course offering rosters after students register o Users of the registration system are assigned passwords which are used at logon validation

Consider a books ordering system in order to purchase books. Process order is elaborate below in order to define the logical functions of the system. First, incoming orders are checked for correct book titles, author's names, and other information and then batched into other book orders from the same bookstore to determine how may copies can be shipped through the ware house. Also, the credit status of each book stores is checked before shipment is authorized. Each shipment has a shipping notice detailing the kind and numbers of booked shipped. This is compared to the original order received (by mail or phone) to ascertain its accuracy. The details of the order are normally available in a special file or data store, called "Bookstore Orders”. Following the order verification and credit check, a clerk batches the order by assembling all the book titles ordered by the bookstore. The batched order is sent to the warehouse with authorization to pack and ship the books to the customer. a)…
Scenario: Consider an appointment system at a medical clinic, where a patient can request to make an appointment to see a certain doctor at a specific time. Additionally, a doctor can use that system to record the timings where he would be available to see his patients. A receptionist can print schedule information for a specific day at that clinic. In one use scenario, a patient will make a request with the receptionist regarding an appointment with the doctor. The receptionist will look up the patient to see if the patient has any bills to be paid. The receptionist will then ask the patient whether he or she wants to set up a new appointment, cancel an existing appointment, or to change an existing appointment. If the patient wants to create a new appointment, the receptionist asks the patient for some suggested appointment times, which the receptionist matches against potential times available. The receptionist finally creates a new appointment. In another scenario, a patient…

Assume you are putting in place for the first time at your institution a new room reservation system that keeps track of which courses are offered in which rooms. Consider that each building is "owned" by a single college or department, and that only one individual within each college or department has the right to assign rooms to that building. Which converting technique would you choose, in your opinion?

Scenario: You are tasked with the development of an E-Scooter ride-share system. It allows registered commuters to approach an idle E-Scooter and reserve it, following which they use the E-Scooter to commute a certain distance (that is not known prior to use). Finally, after the commuter reaches their destination, they end the ride, which prompts an automatic computation of the ride fees. which is automatically debited using the commuters registered payment details. Tak 3 Create an AOM Goal diagram based on your identified Roles and Goals. Please make sure your diagram has at least 3 levels of hierarchy.
A Rent-A-DVD (ARD) runs a series of fairy standard DVD stores. Before a DVD can beput on the shelf, it must be catalogued and entered into the DVD database.
