if it is a one-one relationship we can add decision and date to student class, however if same student is applying for multiple colleges (which is possible) we cannot have that columns in student class ,as is it ambiguous for which college the information is related to . Hope the explanation helps
Great explanation. Thank you kindly.
This was really helpful thanks.
why do we add construct in association class topic?
And why we need to add association class, instead can't we just add decision and date to student class directly?
Perhaps to adhere to relation desgin theories, such as 4th normal form.
