ECS Quiz-5
Consider the following scenario: Organization: MyCo Five Divisions: DivA, DivB, DivC, DivD, DivE Framework: LoanAppFW The LoanAppFW contains an “IsApproved” rule, that directly calls the “GetRating” rule. The requirements for GetRating are different for all five divisions. All work types use these rules. In a best-practice design, how many GetRating rules are there? (Choose One)
Five, in: MyCo-DivA-LoanAppDivA-Work, MyCo-DivB-LoanAppDivB-Work, MyCo-DivC-LoanAppDivC-Work, MyCo-DivD-LoanAppDivD-Work, MyCo-DivE-LoanAppDivE-Work
Six, in: MyCo-FW-LoanApp-Work, MyCo-DivA-LoanAppDivA-Work, MyCo-DivB-LoanAppDivB-Work, MyCo-DivC-LoanAppDivC-Work, MyCo-DivD-LoanAppDivD-Work, MyCo-DivE-LoanAppDivE-Work
Six, in: MyCo-FW-LoanApp-Work, MyCo-DivA-, MyCo-DivB-, MyCo-DivC-, MyCo-DivD-, MyCo-DivE-
Five, in: MyCo-DivA-, MyCo-DivB-, MyCo-DivC-, MyCo-DivD-, MyCo-DivE-
I have confusion with option B and option C . Can any one explain me why the answer is B not C ?

Hi Damah,
There is no doubt that Option C which provides the abstract class model can also hold the GetRating rule and the rule can be easily inherited. But, the question actually asks about a best practice design. Since the rule is to be used by all work types, keeping the rule in work class would actually help in quicker rule resolution.
Hope this helps..
Thanks....
