Question

Please help with Q7.

Problem Statement The Campus Common is a precinct on campus where people can meet, eat, drink, and socialise. An extract from their website: "the Campus Common is the new temporary food, beverage and social precinct on campus for staff, students and visitors to enjoy." you are being tasked with analysing the needs of many stakeholders and coming up with requirements for a system called the "Campus Common System" (CCS) This system will aim to provide a way for students, staff and student groups at the university to book spaces at Campus common for events, order food and beverages and register for university run events. You have been tasked with going through the initial proposal described below and detailing some features and processes that CCS would need to provide. An extract from the proposal University students and staffs do not automatically have an account created in CCS. A student or a staff member can optionally register to CCS to become a CCS Member and start to use its features. In order to register for a CCS account, the student/staff would need to register their details and validate their account with a connection to AuthServer. The reason for this is to cross-check if the student/staff has a valid identification. CCS also allows registration for student group and departments; However, the validation of the group is carried out through a different server, MQAuthGroupAuthServer to cross-check for authenticity Food and beverages could be ordered through CCS. While placing an order, a CCS Member can choose to order food and/or beverages. If it is a student/student group placing order for food, orders have to be pre-paid in advance and it goes through a Bank system. Orders can be picked up or delivered by a CCS Delivery Person. A student can register to be a CCS Delivery Person. Validation of the registration again goes through the same MQAuth server. CSS allows the Delivery person to accept an order delivery and be able to change the status of order as delivered. CCS Members can rate their order and delivery and may choose to write any comments. Restaurants are auto-registered in CCS. When an order is picked up at the counter, the person at the restaurant can use CSS to change the status of the order as picked up. They will also be able to process the payment through the bank when the order is not prepaid. CCS Members can book spaces at Campus common to hold events. They can choose to add Bundles' whilst requesting for an event. If the bundle option is chosen, payment will be processed immediately either through the bank or Budget Office System (if the booking is made by Department/Staff). CCS Members can see the status of their event booking and will also have the option to cancel their event booking. They can also ‘raise a dispute' to help deal with issues/requests regarding their event booking. CCS Managers are responsible for managing event bookings. They create event bookings and manage schedule conflicts. They can deny the event booking request and also can change the status of the event. 07) Draw a Context Diagram (Level 0 DFD) for CCS. Draw a Use Case Diagram for CCS based on the problem statement and extract Also: You need to add two more use cases for a CCS Delivery Person and add that to your diagram. Please add few sentences underneath the diagram explaining the newly added use cases

Answer 1

Case Diagram of CSS:

A Context diagram is a diagram that defines the boundary between the system, or part of a system, and its environment, showing the entities that interact with it. This diagram is a high level view of a system. It is similar to a block diagram.
