A behavioral model diagrams what activities occur within the system. Contrast this to the functional model, which depicts the activities that occur from the user's point of view-the external perspective.
With behavioral modeling, you capture the internal perspective-how activities occur from the system's point of view. Behavioral models comprise communication diagrams and sequence diagrams.
These diagrams show the messages that objects send and receive and the order of those messages. Behavioral models also include state machine diagrams, which indicate what happens to each of the objects in the system once those messages, or interactions, occur.
In this Application, use the WestEast College case to create a behavioral model that depicts the system's interactions with the students. Using one use case as your basis, perform the following steps:
Create a sequence diagram.
Create a communication diagram.
Create a behavioral state machine diagram. Perform a CRUD analysis. Justify the choices you made in your behavioral model.
Briefly explain the relationship between your behavioral model and your structural and functional models you created in the last unit.
Cite your sources according to APA guidelines.
WestEast College Case
WestEast College hires you as a systems analyst to design its new admission/registration system.
WestEast College is one of the top ranked schools in the United States. It is a small private college with nearly 3,000 students, 100 faculty, and 50 supporting staff (including 10 full-time and four part-time IT staff who are responsible for supporting all academic and operational IT needs).
The college accepts new and transfer students from other colleges and countries. The college only accepts online applications.
Once prospective students have completed and submitted their application and the college receives it, they submit additional documentation such as transcripts, recommendation letters, a personal essay, residency information, proof of language proficiency, and financial aid documents.
Once students are accepted, they take a placement test for math and English. If students pass the required tests, they are assigned general education classes (such as math, English, and social studies). If they do not pass a subject, they are assigned intensive classes in the failing subject.
Students progress through four years of classes and must maintain a 2.00 GPA or they are placed on probation for 2 quarters. If they drop below 2.00, students are dismissed. They must score at least a C to move to the next class or they must repeat the class (a D is not an acceptable grade).
Students must finish their degrees in no more than 5 years and cannot switch majors more than twice.
Students eligible for graduation must pass an assessment test in their major before they may graduate.
