Diagram:

Method:

I took the information such as names and function names from my SRS Activity Diagram as well as from the SRS Requirements given in the files.

            Associations:

The course as used in the class: I applied a frequent association with one in relation to the much cardinality because one is required to only work with one course as he or she progresses to the other one.  

Class to Online Class and Face-To-Face Class:

I decided to use a parent to the child connection because a class usually comprises of either online or face-to-face.

Student registration, the course and class:

In this section, I used aggregation associations from the Student/Course/Class in the process of registration. I did so because during registration process one will be required to access a section of the available classes but not the whole class. This method also looks more appropriate. 

Student Registration or Course cardinality:

 In this section, I came up with a specified number 1 to 1 because it applies to every registration record and that there can only be a single student and a single course that they will be registering.

Class cardinality Registration:

Sometimes students end up registering multiple classes; therefore, I used this method so that the entire student can pass the rules of validation.

CRC Cards:

            Name: refers to class name

            ID: I used a 1-6 sequential (ID) identification

Kind: having an exclusion of the “class” on the CRC card, I assigned all the Domain. I used Concrete because it is obvious that these objects have to be able to be formed because the domain itself is in the work domain.  

Besides application of the basic information as well as the Registration card, the remaining CRC cards ought to be clear as I went through the diagram several times.

Registration the card involves additional rationalization because the attributes given were not given as a component of what is needed however; they had to be independently determined.

            Student ID: It identifies the specific student registering.
            Course ID: It identifies what is being registered for.
            Registration Date: It identifies the specific date that the student registered
            Student GPA: It identifies the student’s current GPA for validation function.

I left out some of the things such as terms and conditions because it is not in the requirement. In this case, I assumed that the terms and conditions has already been analyzed and understood during the display courses as well as in the time of class displays and that they are already taken into consideration through the process which is found outside this assignment’s scope.
