Business Delegate and Factory

No, I don't agree with u. I feel that BDO just decouple Presentation
layer and business layer and not implementing any logic inside.
Generally no change require in BDO through out the software life accept
you change interface with business tier. Factory should use when we want
to dynamically change serving object and that is not the case with BDO.
Addition to this static relationship is always faster then factory. So I
suggest
public void performAction(...){
 CustomerBD customer = new CustomerBD();
}

Instead of

public void performAction(...){
 BDFactory bdf = new BDFActory();
 CustomerBD customer = (CustomerBD)bdf.createBD("customer");
}

What is expert's opinion?

Regards,
Nishi

Subject: Business Delegate and Factory

Hi Folks
I wish I know what the best form to create a instance of a Business
Delegate
object(BDO).
In the samples, I always see that the BDOs are created directally like
this:

public void performAction(...){
 CustomerBD customer = new CustomerBD();
}

But I think that a Factory could be better. am I right ? like this:

public void performAction(...){
 BDFactory bdf = new BDFActory();
 CustomerBD customer = (CustomerBD)bdf.createBD("customer");
}

I think that this form I have a unique place to create my BDOs.
