L A B O V E R V I E W 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.

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.

CIS/339 iLab 2 of 7
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.
CIS 339iLab 3 - 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.
Deliverables
Class diagram for the SRS system
CRC cards for each class in your class diagram
STEP 2: Create the Class Diagram
Download the CRC Card Template and use it for your deliverables this
week. (Attached)
Explain your work and the decisions you made to arrive at your
proposed solution.
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.
Explain your work and the decisions you made to arrive at your
proposed solution.
STEP 4: Copy the Diagram into an MS Word document
CIS 339iLab 4 - 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.
Deliverables
Sequence diagram for the Register a Student for Classes use case
Communication diagram for the Register a Student for Classes use case State

STEP 2: Create the Sequence Diagram
Create a sequence diagram for the Register a Student for Classes use
case using the Rational Software Architect software in the Citrix iLab
environment. Explain your work and the decisions you made to arrive at your
proposed solution.
STEP 3: Create a Communication Diagram
Create a communication diagram for the Register a Student for Classes
use case using the Rational Software Architect software in the Citrix iLab
environment. Explain your work and the decisions you made to arrive at your
proposed solution.
STEP 4: Create an Object State Diagram
Create a state machine diagram for an object of the Registration class
(the class that maintains the registration of a student in a class) using the
Rational Software Architect software in the Citrix iLab environment. Explain
your work and the decisions you made to arrive at your proposed solution.
STEP 5: Save and Upload the Project
CIS 339iLab 5 - Package Diagrams
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.
Explain your work and the decisions you made to arrive at your
proposed solution.
CIS 339iLab 6 - 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 CourseList and the Course classes for your
demonstrations. The CourseList class maintains and populates the current list
of courses that the end user is working with while registering for clases. 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.

STEP 1:
Create a Public Method Contract
Download the CRC Cards for the CourseList and Course classes and
review them to prepare for your deliverables this week. Download the Method
Contract Template and use it for your deliverables this week. Create the method
contract for the GetCourseByCourseID() method of the CourseList class. Explain
your work and the decisions you made to arrive at your proposed solution.
STEP 2:
Create a Method Specification
Download the Method Specification Template and use it for your
deliverables this week. Create the method specification for the
GetCourseByCourseID() method of the CourseList class. Explain your work and the
decisions you made to arrive at your proposed solution.

CIS 339iLab 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.
Deliverables One Word file that contains the following. A copy of the
code you wrote for the GetCourseByCourseID method() of the CourseList class in
your favorite OO programming language A screen shot of the output of running
the provided unit test in the shell (the CourseListTest class) showing that
your code works as expected. Note that these unit tests only print out messages
of testing problems. If your code is correct, the unit tests will succeed
silently without any success messages. An explanation of your work and the
decisions you made to arrive at your proposed code A zip file of the completed
shell after you added your code so that the shell could be executed on a
different machine i L A B S T E P S
STEP 1: Review the Method Contract, Method Specification for the
GetCDByCDID() Method, and Coding & Unit Testing GetCDByCDID() Method using
Java (not Graded)
Download the Method Contract for GetCDByCDID() Method and review it
prior to reviewing this week’s video tutorial. Download the Method

STEP 2: Code & Unit Test the GetCourseByCourseID() method of the
CourseList class
Decide on your OO programming language that you will use for this lab
and then download the corresponding shell from the following.
Visual Basic Shell C# Shell Java Shell
Both the Visual Basic and C# shells are Visual Studio projects while
the Java shell include only the *.java source files that could be loaded into
any Java IDE.
Code and unit test the CourseList.GetCourseByCourseID() method in your
favorite programming language. You only need to add code for the GetCourseByCourseID()
method and then run the application (the unit test will automatically test your
code), then print out problem messages, if any
