Please briefly explain why you feel this user should be reported.
Suppose you have a profile for an application. This profile stores some data specifically about one user. You can persist the details of the profile and pull them back each run.
Does a profile make a good candidate for the State pattern? If not, is there a good heuristic to model this sort of functionality?
State design pattern works in case of number of internal states through which your object pass so state design pattern is not applicable here.
You may only need a profile class with respective properties and a DTO object which can store profile object and retrieve it.
It’snot necessary to use a design pattern in a certain problem IF you have small and simple design , implement simple design it will definatley gives you more control over your design.
