Relationship between UsesCases - Include - Extend - Lets assume for the elective subject if the student enrolls he has to pay fee in two installments first installment at the time of enrollment and second installment before the exam - Pay fee (New Use Case) - So Enrollment is the Including Use Case and Pay Fee is the Included Use Case Enrollment --- Pay fee Credit Card or he can pay fee by Debit Card Credit card payment and Debit card payment www.qbi.in
