Week 1—System Request
1

Use this system request template and complete the SRS system request.

System Request—

Project sponsor:

School of Prosperity (SoP)

Business Need:

The existing desktop system will be upgraded to web-based application and this system will be used to maintain records of students, courses, classes, and student registration and grades.

Business Requirements:

The system is capable of having the following functonalities:

· Accessibility over the Internet

· Maintains records of school students

· Maintains records of courses offered by school

· Maintain records of classes offered of the above courses (both online and face-to-face classes)

· Students registration system is included as well

Business Value:

Conservative estimates of tangible value to the company include:

· The SRS will enable the school to continue the expansion of its student population and to effectively manage the expansion

· Eliminate many school staff hours re-entering paper form student registrations by allowing the students to self-register

· Make the system easy to access from anywhere there is an Internet connection and a web browser

Special Issues or Constraints:

· The SRS must be able to handle both online and face-to-face class offerings

· The system must be accessible over the Internet to both school staff and students each with appropriate permissions

· The SRS must try to integrate with and re-use existing desktop application code and database as much as possible to reduce development cost

2

Validate and verify that your system request addresses the SRS Preliminary Planning Overview.

The business need area explains what the SoP is requiring the system to operate. The business requirements consist of what the system must be able to handle and the expectations of the system (once it’s completed). The business value breaks down the details of information that the new system will save on both staff hours and finances for the school. The issues area give problems that could exist once the system is implemented.

3

Explain how you completed your work, the decisions you made to arrive at your conclusions, and the lessons you learned.

I, carefully, read the SRS Preliminary Planning Overview and highlighted the important business needs that the SRS system is to meet. I then started to complete the various sections of the System Request Form and while doing so, I referred back to the SRS overview document to confirm my conclusions and understanding. The result of this iterative process is the current System Request Form.

Week 2—Use Case Diagram and Use Cases Descriptions
1

Generate a use case diagram for all of your use cases, including their actors. The diagram must be generated by a UML drawing tool. Copy and paste your diagram here:

SRS Use Case Diagram

Register a Student for Classes

Use Case Name: Register a student

ID: 2

Importance Level: 1

Primary Actor: Staff Member

Use Case Type: Fully Dressed

Stakeholders and Interests: Staff Member/ Student

Brief Description: This use case covers the registration process of a student using SRS.

Trigger: Register Student Button

Type: Fully Dressed

Relationships:

Association:

Include:

Extend:

Generalization:

Normal Flow of Events:

1. A staff member or student logs into the system.

2. A list of available courses offered are displayed.

3. User selects a course from the list and all the offered classes for the course are displayed.

4. User can select class from the class list.

5. The selected class to registration for is then validated against the registration rules

6. When the registration is valid against the rules, a registration record is created and a message is then displayed to confirm registration.

7. If registration is successful, one is added to the number of students that have enrolled in the class.

8. After the student completes the class, his registration record is updated with a grade. But the student has the option of dropping the class while taking it.

SubFlows:

5.1. No duplicate registration for the same class

5.2. Online classes registration requires students acknowledgement that they have the required hardware and software to access online classes

5.3. No more than three class registration for open classes unless student GPA is greater than 3.0. Then the student can take four classes.

5.4. The student has taken any required pre-requisite course.

Alternate/Exceptional Flows:

6.1. A message explaining the violation of the associated rule is displayed.

2

Validate and verify your use case diagram and use case descriptions against the SRS Requirement Definition and the SRS System Request.

SRS has 4 major functionalities which are covered in the 4 use cases, which are as follows:

Functionality

Covered in Usecase

Maintain Student Records

Maintain Student Records

Maintain Course Records

Maintain Course Records

Maintain Class Records

Maintain Class Records

Register a Student for Classes

Register a Student for Classes

3

Explain how you completed your work, the decisions you made to arrive at your conclusions, and the lessons you learned.

I first read the case thoroughly and then listed all the functional and non-functional requirements on the page. Then I extracted the major use-cases from them. After that I generated the flows for those use cases. After extraction of the major use-cases and their actors I build a use-case diagram and after getting the flows I end up getting the fully dressed use cases.

Week 3—Class Diagram and CRC Cards
1

Generate a class diagram for the SRS system. The diagram must be generated by a UML drawing tool. Copy and paste your diagram here:

SRS Class Diagram

Use this CRC template and complete a CRC card for each class you designed in your SRS class diagram.

2

Validate and verify your class diagram and CRC cards against the SRS use case diagram and use case descriptions.

There are 4 major use cases, so for each case there can only be one class, because each use case is about updating the entries for one entity.

There is one CRC card for each class and every detail about that class is written there.

3

Explain how you completed your work, the decisions you made to arrive at your conclusions, and the lessons you learned.

The decisions I made are quite simple. Because I created all the necessary classes and made the association relations in between them. Then I made CRC cards for those classes.

Week 4—Sequence, Communication, and State Machine Diagrams
1

Generate a sequence diagram for the SRS system Register a Student for Classes use case. The diagram must be generated by a UML drawing tool. Copy and paste your diagram here:

Sequence Diagram for the Register a Student for Classes Use Case

C:\Users\Inam Baig\Desktop\sequence.jpg

Generate a communication diagram for the SRS system Register a Student for Classes use case. The diagram must be generated by a UML drawing tool. Copy and paste your diagram here:

Communication Diagram for the Register a Student for Classes Use Case

C:\Users\Inam Baig\Desktop\communication.jpg

Generate a state machine diagram for the SRS system RegistrationRecord object/class (the class that maintains the registration of a student in a class). The diagram must be generated by a UML drawing tool. Copy and paste your diagram here:

State Machine Diagram for the RegistrationRecord Object

2

Validate and verify your behavioral diagrams against the SRS Register a Student for Classes use case description and the SRS class diagram.

All the diagrams match with the specifications in SRS. As in the communication diagram all the communication path of register a student use case is shown. Moreover in the sequence diagram the path of use case Register a student is shown according to the classes in class diagram. In state diagram all the states are shown in a sequential way.

3

Explain how you completed your work, the decisions you made to arrive at your conclusions, and the lessons you learned.

I just understood the use case register a student and its path, after that I mapped that path in the form of classes in the class diagram. After that according to the paths and classes I mapped these in the form of diagrams.

Week 5—Package Diagram
1

Generate a package diagram for the SRS system. The diagram must be generated by a UML drawing tool. Copy and paste your diagram here:

SRS Package Diagram

2

Validate and verify your package diagrams against the SRS class diagram and the SRS Register a Student for Classes use case sequence and communication diagrams.
