Ok, so the BasicDAOImpl is the 'helper' that you are talking about.
Since you mentioned this is wrong:

If the above is wrong, where then in BasicDAOImpl would
the conversion be done to transform annualSalary into salaryPerWeek?
Also you mention:
> BaseDAOImpl stores reusable parts that are common to all concreate
> DAO's thus name is Base.
Right that makes sense, but then you seem to be saying that BaseDAOImpl
(the helper) would take care of something specific like a conversion of
annualSalary to salaryPerMonth? That's such as specific thing why
wouldn't that be moved somewhere else (like the adapater class that I
created above..or maybe even moved directly into the main DAO that
extends BaseDAOImpl.
Can you give an example of what class and where in that class (what
method) would take care of doing a conversion like above?
