Answer / rahul
The most important technical distinction between creating a
derived class and implementing an interface is that a
derived class can only inherit from one base class, but a
class can implement any number of interfaces.
From a design standpoint, think of inheritance as expressing
a specialization hierarchy. If WebSalesOrder "is a" special
kind of SalesOrder, you might consider making it a derived
class.
However, you need to be very careful that you don't use
inheritance when the specialization that distinguishes a
derived class from a base class is a feature that other
classes will also need to support. For adding those kinds of
features or capabilities to a class, implementing interfaces
will give you much greater flexibility.
