Object Modelling and Design for University Enrolment System

This project presents an object-oriented model for a university enrolment system, designed to streamline the enrolment process at National University. The project begins with an analysis of functional and non-functional requirements, detailing aspects such as student data input, course management, payment processing, and system usability, reliability, performance, and supportability. It then develops use case diagrams, use case descriptions (including a fully developed sign-up process), and a UML class diagram to visually represent the system's components and interactions. An event partitioning diagram for the sign-up process further illustrates the system's workflow. The project aims to facilitate online enrolment, providing a user-friendly and efficient experience for students while assisting the university in managing enrolment data and student preferences. This comprehensive approach covers the key elements needed for developing a robust and effective enrolment system.

1. Functional and Non-functional Requirements
The national university enrolment system that is being proposed includes functional
requirements that are included in the system. Some of the functional requirements are listed
below:
 The system has the capability to take the input of the students so that they can be
registered on the database system of the enrolment system.
 All the details of the student is stored in the system along with the course details that the
students selects.
 The course details are also stored in the system database from which the students selects
their choice of course.
 Each course has different terms and all the terms details are also shown by the system
while taking the details of the course.
 Each class should have maximum total number of students as 40 and when the count is
finished, the system will exclude that particular course from the list.
 The final details of the students showing the course details and term details are shown by
the system before making the payment for the system.
 The enrolment system will allow a particular student to select a maximum of three or four
subjects from all the available courses.
 Necessary changes are allowed by the system if required before proceeding with the
payment of the course.
 The system allows three types of payment procedure, one is debit card payment, direct
account payment and master card payment.

3OBJECT MODELLING
 When there is debit card payment and master card payment, the system asks for the card
details from the user to proceed the payment method.
 The system has also the ability to store the details of the card for paying in future. For
that the student only needs to enter the one time password of the card from the registered
mobile number and complete the payment. The details of the card is not needed to enter
over and over again for paying in future. This saves a lot of time.
 The system shows the dates, the academic details of each terms, details of the library,
details of orientation week on the screen so that the registered students may get the
details from the system.
Along with the functional requirements, there are also non-functional requirements that
are enrolment system of the National University includes. Non-functional requirements includes
a feature known as FURPS+. The F in the FURPS+ feature includes the functional requirements
that is explained above. The “URPS+” stands for usability, reliability, performance and
supportability. All the features of the non-functional requirements are explained below:
Usability: Usability includes accessibility of the system, aesthetics of the system and
consistency related with the system. The enrolment information system that is included in the
system support the usability constraint of the non-functional requirement. All system that is
being proposed will have a good user interface so that students can enrol themselves easily. The
information system also has a documentation so that it becomes easier for the stakeholders to get
to known about the usability of the system that is being built for the enrolment system. All the
standards of the user interface will be satisfied using the enrolment system.
Reliability: Reliability refers to the system being secured and safe so that the users can
use it safely. Reliability occurs when the system is secured and there is no fear of data breach in

4OBJECT MODELLING
the system. The enrolment information system that is being proposed for the national university
will satisfy the reliability constraint of the non-functional requirement. The enrolment system
will be safe as well as secure so that the data of the system will be secured from the attackers and
there will be proper security measure taken to prevent the system from being attacked.
Availability of the system will also be robust to the students as well as the staffs associated with
the National University.
Performance: The performance constraint of an information system states that the
system can be used by many concurrent users at the same time. The information system that will
be designed for the National University will satisfy the performance constraint as the system and
will support many concurrent users at the same time. Many users can use the system information
system for conducting the operations of the information system. The system will be accessible
online and the response time of the system will only be some fraction of seconds for navigating
through the pages.
Supportability: The last constraint of the enrolment information system that is proposed
for the system includes other constraints such as configurability, installability, maintainability,
testability, adaptability, scalability and compatibility. The system will be designed with the help
of relational database that will include coding as well as construction of the system. The
implementation of the system requires the standards, the platform that is needed for system
implementation, and the language of implementation that is being used by the system. The
enrolment system will also support different human languages and will be available for almost
all the time. The system will also include visual basic for the implementing the presentation logic
of the information system.

2.2 Use case Description
Use case Use case Description
Sign up The sign up process of the information system
will include the sign up process where the
customer will sign up for completing the
registration.
Login The system will have to complete the login
process for selecting the course details and the
term details. They also have to login for
getting the other details related to the
university and the course.
Course Details The student needs to get the course details of
the university so that they can enrol
themselves for the course.
Term Details The student also get to know about the term
details of the course. The student needs to
request for getting the course details.
