Scenario and Summary
You have been hired by the School of Prosperity (SoP) as a software architect to help the school plan, design, and implement a new online system called the Student Records System (SRS).
The Student Records System (SRS), described in the SRS Preliminary Planning Overview document, is the 7-week-long project that you will work on throughout this course. You will be developing UML models and documents for the planning, design, and implementation phases of SRS development.
In each week, you will be provided with the information you need to continue to develop your analysis and design UML models and documents for this project.
In this very first week, you will develop the System Request document that articulates the business needs and values of the SRS. The Sop school is excited about this project and allowed you to ask them five questions to clarify project issues for you about the SRS project. You are to include these five questions in your submitted System Request.
Complete the System Request Form for the SRS, including your five questions.

Student Records System SRS - Preliminary Planning Overview
The School of Prosperity (Sop) is a small Information Technology & Science school located in the nation’s capital of Washington, D.C. The school serves a growing student population of about 5000 students by offering programs leading to the Bachelor and Master degrees in IT and Software development.
SoP has, traditionally, offered most of its classes in a face-to-face modality. Recently and because of the increased demands of student enrollments, the school started to offer some of its classes online as well.
The school staff currently uses an in-house desktop application to keep track of students, courses, and to register students for classes. School staff has to be physically in the office in order to access the in-house application. To register for a class (either face-to-face or online class), a student must complete a paper registration form, submit it to the school staff, and the staff will then enter the registration information into the desktop application.
This process always generates many errors in moving from the paper form to the electronic registration filing. Moreover, since there are so many add/drops at the beginning of each semester, the school staff experiences a higher than normal work volume handling these add/drop forms preventing them for completing other tasks allocated to them like staff development and training.
To keep up with the high demands of increased enrollments and to allow students to handle their own registrations online, SoP decided to invest in a new Internet-accessible Student Record System dubbed SRS.
The SRS is to maintain records for students enrolled in the school, courses offered by the school, classes offered of these courses in the two modalities of online and face-to-face, and student grades for the classes that they have completed. The SRS should be Internet-accessible and thus allows students to self-register directly for their own classes and allows the staff to work from any location that has an Internet connection and a web browser.

Use Case Diagram and Use Case Description
Work has already started on the planning phase of the Student Record System (SRS) for the School of Prosperity (SoP) and everyone is excited about this new system.
As the software architect of this project, you met with many users and stakeholders of the old system to determine the requirements of the new Internet-accessible SRS software system. Your meetings and requirement-gathering efforts resulted in an SRS Requirement Definition document that summarizes all of the requirements of the project.
One of your development team members was excited about this project and wanted to start working on it immediately. She therefore took the initiative and created a high-level business process activity diagram for the SRS system. You reviewed the activity diagram and found it to be a good foundation from which to create the SRS use case diagram and the SRS use case descriptions.
There is still work to be done to complete the Functional Modeling of the SRS. Your deliverables for this week’s iLab are the SRS use case diagram and two use case descriptions for the Maintain Class Records and the Register a Student for Classes use cases.

STEP 3: Generate the Use Case Descriptions
Create use case descriptions for the two major use cases in the SRS system. These two major use cases are the Maintain Class Records and the Register a Student for Classes use cases. See the Figure 5-5 example in the text.
STEP 4: Copy the Diagram Into an MS Word document
Be sure to include all deliverables in one Word document. Copy and paste the use case diagram into the same Word document that contains the use case descriptions. Save your document with the file name CIS 339_Lab2_YourName.

Structural Modeling Class Diagram and CRCs
As the software architect for the SRS system, you are making good progress in your work. After finishing the Functional Modeling (activity diagram, use case diagram, and use case descriptions) of the SRS system, you are now ready to move on to its Structural Modeling.
In this week, you will use the models of your Functional Modeling to determine and design your class diagram and complete a CRC card for each class. The Structural Modeling is very critical for the success of your project since it is the backbone upon which the entire project is built, so take the time to design and refine your class diagram and its corresponding CRC cards.

STEP 3: Complete the CRC Cards
Create CRC cards for each class that you designed in your class diagrams, ensuring that you identify all appropriate attributes, operations, relationships (including types), responsibilities, and collaborations. Be sure that you complete the front and back of each card. Be sure that your CRC cards exactly reflect what you created in your class diagrams.
STEP 4: Copy the Diagram into an MS Word document

Sequence, Communication, and State Diagrams
In this week, you will use your functional and structural models as the basis for your behavioral models that need to be developed for the SRS system. Specifically, your deliverables for this week are designed to develop these two behavioral diagrams for the Register a Student for Classes use case.
Sequence diagram Communication diagram
In addition, you will also need to create a state machine diagram for the Registration class (the class that maintains the registration of a student in a class).
These behavioral model and diagrams are major milestones in your architectural and design work. They give you your first opportunity to verify that your use case (in this case, Register a Student for Classes) could actually be implemented using the objects of your class diagram design. If you reach this verification, then you are done with the analysis phase of your SRS project.

Your analysis phase of the SRS project went well and your team feels good about their Functional, Structural, and Behavioral models. You also discussed the result of your analysis with the School of Prosperity (SoP) administration and they seem to be in line with your analysis models.
Now is the time to start the design phase where you generate specific directions for the implementation of the system by the software development group. The first step in the design phase is to examine the SRS class diagram and to try to simplify its organization using a package diagram. The package diagram ensures that classes that belong together are grouped into a single package and thus simplify the development of these classes and their maintenance.
Your deliverable this week is to generate a package diagram for the SRS system.
Create a package diagram of the SRS system (to simplify the SRS class diagram) using the Rational Software Architect software on the Citrix iLab environment.

CRCs Contracts and Method Specifications
The design phase of the SRS project is in full swing and every developer on the team is assigned a group of packages to work on and to complete the design details of the classes in the package. To help speed up the design process, you—as the software architect of the project were assigned the task of providing a sample method contract and a sample method specification to demonstrate to your team how these two documents are developed.
You decided to use the Course List and the Course classes for your demonstrations. The Course List class maintains and populates the current list of courses that the end user is working with while registering for classes. You will demonstrate the contract and the specification of the GetCourseByCourseID() of the CourseList class.
The GetCourseByCourseID() method searches the current list of courses for a course whose CourseID matches the ID supplied to the method. If a matched course is found, it is returned by the GetCourseByCourseID() method; otherwise a null value is returned, indicating there are no matching courses.

CIS 339 DeVry Week 7 iLab 7
Object Oriented Application Coding
Your demonstrations of how to create both method contract and the method specification for the GetCourseByCourseID() method of the CourseList class were very well received by your team members. They then asked you for one final demonstration of how to implement the method specification using an object-oriented (OO) programming language and see the method actually execute.
You realize that it is easy to implement the method specification in an OO programming language, but it is hard to test it because the rest of the application is not developed yet. You decided, therefore, to write two pieces of code.
Code that implements the GetCourseByCourseID() method Code that implements a unit test for that method alone (outside of any other application code)
This way you can demonstrate the method implementation and also verify its correct behavior.
You are under a deadline constraint for this deliverable, so you asked some of your peer architects for help. They each are well versed in different OO languages like VB.NET, C#, and Java and they all have done unit testing before so they are familiar of how to construct one.
Your peer architects provided you with partially-completed shells for your demonstration. Each shell contains:
Complete code for the Course class; partially completed code for CourseList class; and complete code for the CourseListTest class that unit tests the CourseList.GetCourseByCourseID() method.
Your task is now easy. Just select one of these shells and complete the code for the partially completed CourseList by coding it GetCourseByCourseID() method. When you compile and run the shell, it will automatically test your GetCourseByCourseID() code to ensure its correct behavior.
