Abstract

Design Patterns are considered well established mechanisms for software reuse and evolution. However, more recent researches show that although the design of these patterns is reusable, their implementation is not. Some authors have showed that object oriented implementation techniques are not suitable to implement design patterns because they do not have mechanisms to handle orthogonal concerns to the pattern´s main interest. Aspect oriented programming techniques provide language constructors more suitable to encapsulate this type of behavior, thus supporting reusability of the pattern’s code. This paper presents a proposal of aspect-based design for the Persistence Layer design pattern and some guidelines that help creating an aspect-based design from an object-oriented system developed reusing a specific design pattern.

Keywords: Design Patterns, Aspects, Persistence Layer, Persistence, Modularity
