Both are different design pettern. name drives their
functionality.
Business Delegate : it is used decouple presentation and
business layer. it avoids to intract presentation client to
understand your business services.
Data Access Object : DAO is used on database layer,
generally it is used to avoid database intraction by EJB or
Business Object. it is used to retreive and store data.
mostly I preferred, DAO is used with Value Objects
