Question

1.   Think about the system that handles student admissions at our university. The primary function of the system should be able to track a student from the request for information through the admissions process until the student is either admitted to the school or rejected.

II.   Write a use-case description that can describe an Admit Student use case.
Assume that applicants who are children of alumni are handled differently from other applicants. Also, assume that a generic Update Student Information use case is available for your system to use.

III.   Create a use-case diagram that includes all of the above use cases.
Assume that an admissions form includes the contents of the form, SAT information, and references. Additional information is captured about children of alumni, such as their parent’s graduation year, contact information, and college major.

VI.   Create a class diagram for the use cases identified with questions 2 and 3. Also, be sure to include the above information.
Assume that a temporary student object is used by the system to hold information about people before they send in an admission form. After the form is sent in, these people are considered students.

V.   Create sequence diagrams for the scenarios of the above use cases.

VII.   Create a communication diagram for the scenarios of the above use cases.

VIII.   Create a behavioral state machine to depict a person as he or she moves through the admissions process.

XI.   Perform a CRUDE analysis to show the interactivity of the objects in the system.

Thanks!

Answer 1

Solution:

I. Track Student Information:

1. Given Student Admission System where an eligible candidate can apply to the University for admission by filling the Student Registration form

2. Then the admission system verifies the candidate eligibility criteria then admission conformed then candidate become student

3 If the candidate is a child of Alumni of university, Parents information also to be furnished

4. Priority will be given to the children of alumni

5.A candidate can track the status of admission using application ID

6 Result of Track request is : 1.Received Application and Under Process

2. Accepted and Admission has given

3 Rejected Admission and Reason

Q.no II)

Answer: Use Case Description for Admit Student Use Case:

Use Case is a set of sequences of actions performed by a system with respect to an actor to perform a specified task.

Actor : Is a human being or Hardware or software Element performs a cohessive set roles in the system

Student Admission System :

Actors : 1.University

2. Candidate

3. Student

4. Admission Coordinator

5 Admission Process Software

Use Cases :

1.Registration of A candidate (login)

2. Apply (College,Course)

3. Pre Requisite Info for Admission

4. Other Details ( Alumni's Child)

5. Process Admission(Student Admit)

6 Status ( Track )

7. Log Out

Use Case can be described in Textual Manner or Using Interaction Diagrams can be used to describe a use case

Textual Description Contains Two Elements :

1 Main Flow of Events ( All constraints are True)

Eg: Student Admit Use Case:

Pre Requisite: Candidate Register and apply for admission

i). Receive Application (online) ( Assume Applied)

ii). Verify Mandatory information given by the student ( Assume All are Valid)

iii).Check Eligibility for Applied Course (Assume Eligible or not Eligible)

iv). Accept and Admit Candidate by allocation of Student status ( If he is Eligible)

v). Reject Admission( Not Eligible )

2. Alternate Flows of Events (For each constraint False)

1. If no candidate not Applied - No Admissions - End admit Process

2. More Candidates applied - Check Eligibility ( No one eligible)- End

3. Check student is child of Alumni( Yes)

i) Check Parent College,Major(Course) info ( Valid)

ii) Allot admission under Alumni(parent) quota

Q.No III) Use Case Diagram For Student Admission Process:

Use Case Diagram contains A set of use cases ,Actors and their relationships as shown below:

IV) Class Diagram for Student Admission Process:

Class diagram Contains A set of Classes and their relationships as shown below:

The above Student Admission System Contains the following Classes:

1. Student

2. Candidate

3.Application

4 Alumni

5. University

6. Dean Admissions(Or Registrar)
