1.6.1.2 SEPARATING CONCERNS ALLOWS APPLICATION LOGIC

AND PLATFORM TO BE VARIABLE AND ENCOURAGES RE-USE

It is observed that design pattern tends to integrate the behavior aspects

with implementation aspects which result in risks of platform changing

or volatility. Further, some implementation details become suppressed

as consequence of behavioral variation as in the publish-subscribe pattern

which does not say anything about remote objects design [15]. If this pattern

is used in a distributed environment it becomes necessary to distinguish lo-

cal from remote objects which is not available as a design decision at design

time.

Design Pattern follows a life-cycle as patterns ...
