Problem Statement

A specific university houses approximately $2000$ students. The current system of accommodation

application is not yet computerized and this has made the process of application to be time consuming and

costly$.$ The Student Affairs Office aims to develop an online$-$based Student Accommodation Management

System $($SAMS$)$ to facilitate application for accommodation, while significantly reducing the timeconsuming manual processes for residence administrator. The Student Affairs Office requested to develop

a user$-$friendly website using a PHP & MySQL as a development tool, and Apache as the web server.

Users should be able to access the online portal through a device of their choice $($desktop or mobile phone

browser$).$ The development of this system focuses on security of the information; hence, access rights are

attributed to students and residence administrator. The system enables authorized users to login by

providing a user ID and password in order to access the portal user account.

Student Accommodation Management System enables students to book accommodation by submitting a

form, providing essential details such as their name, student level $($undergraduate or postgraduate student$)$

email address, preferred room type $($private room or shared room$),$ and accommodation beginning

academic term $($Spring or Fall$).$ Depending on the data entered and subject to the availability of a suitable

room, the request may be approved or rejected. Students can check on the status of their application at any

time by logging into their account. Once the application has been approved, students will receive

confirmation e$-$mail with details of their accommodation. Then, students are required to pay the semester

accommodation fees. Students can make an online payment through the system by providing their credit

card information. However, if the student cannot be accommodated, the system should generate an

apology message.

The Student Affairs Office is committed to offering an exceptional student experience to all residents

during their stay. With $2000$ students, they recognize that it is inevitable that on occasion a complaint may

arise and they welcome feedback as a means of improving the service to their residents. Any student that

is currently residing in the accommodation can use the system to submit a complaint to the residence

administrator. SAMS enables students to fill in a form with the student room number and a description of

their complaint. This procedure should be used to address maintenance problems that may occur to their

rooms, such as requesting to fix fused lights, non$-$functional air$-$conditioner, or non$-$functional water taps

etc. For this, round the clock operation of the system is required and downtime shall not exceed two hours

per month. Considering that about $2000$ students live in residence, the response time of the website must

range between $200$ milliseconds and $1$ second to provide a smooth and responsive user experience. The

system shall also perform an automatic restart in the event of a fatal system error, to be completed within

two minutes.

Residence administrator can view all the received requests through the system. For booking

accommodation requests, the residence administrator will review applications and either approve or reject

them. Once allocated a room, the residence administrator will then confirm booking by sending a

notification $($confirmation email$)$ through the system that contains details of room allocations and ask

students to make the payment. The residence administrator should also be able to view the maintenance

requests and post his respond to each complaint.

II$.$ Project Description

For this assignment $($Assignment $3),$ students are requested to draw a UML software class diagram of the

student accommodation management system $($Note: You may have your own assumptions for the

attributes and methods; Be creative and add those you think should be included to make the system useful

and appealing$).$

Moreover, students should draw the object diagram for the system, in which you may have your own

assumptions for the attribute values. $($Note: You should show only one instance object for each class$)$

In addition, students are requested to draw a state diagram to represent all possible transition states a

system can have for the booking accommodation $($application form$).$

You must follow the guidelines for drawing the class, object, and state diagrams mentioned in lectures

and book. Please note that negative points will be assigned to assignments that contain poorly drawn or

low quality resolution diagrams. Hence, it is recommended to use any available diagram tools to draw

your diagrams.

Three diagrams to represent the following:

a$.$ Diagram $1$: Software class diagram for the system.

b$.$ Diagram $2$: Object diagram for the system.

c$.$ Diagram $3$: State diagram for the booking accommodation $($application form$).$
