Designing Strategy 


An object-oriented system might use an abstract base 
class to provide a common and standardized interface 
appropriate for all the external applications. 

Then, through inheritance from that abstract base 
class, derived classes are formed that operate similarly. 
The capabilities (i.e., the public functions) offered by 
the external applications are provided as pure virtual 
functions in the abstract base class. The implementations 
of these pure virtual functions are provided in the 
derived classes that correspond to the specific types 
of the application. 

This architecture also allows new applications to be added 
to a system easily, even after the system has been defined.
