I am using the Facade Pattern to create a web application in Struts.
I've got 3 sets of classes:
Database classes to fetch data from the database
Action Classes to display data on the web interface
Facade class which uses objects of the database classes and gives a set of functions to the Action Classes.
Should I create the objects of the Database classes directly in the Facade class or should I use an interface for the Database classes in the Facade class?
I want to do this so that if I want to use any object of the Database class directly in the Action Class(through the Facade Class that is...) then I dont have to access the Database Class Objects directly in the Action Class.
