An Example Of Software Pattern
Following example illustrates two specific design problems from
different domains of software engineering and knowledge engineering
abstract to a generalized design problem that can be solved succesfully
using a design pattern
First problem:
Designer of a intelligent software system wants to
develop an explanation generator that can generate explanations for
different users.
Second Problem:
Design of the format converter in a
document-processing
system. A document in a certain format should be converted to many other
different formats, and it should be easy to extend the converter when it
has to support another new format.
