Hi Ranchers..
What is the different between Facade & Business
Delegate
Pattern & Data Access Object ?
They look the similiar.
They add a layer in the middle,
and to encapsulate sub-system to make it
easier to use and protect client-app of
changes in sub-system.
In My opinion the different is DAO for Data Access purpose, and Business Delegate is for Bussiness logic purpose. And Facade is
for General Purpose.
So it means DAO & Business delegate are
subset from Facade ?
So DAO & Business delegate = Facade ??
Please give me a light about this problem
Thank you...
