Modeling history sensitivity and orthogonally restricting aspects

Abstract

In this paper, we describe evolution problems of typical software, concentrating on history sensitivity. We start with a basic Object-Oriented design for a simple game. Then, history sensitivity problem is introduced gradually as evolution scenarios. If two different history sensitivity concerns are semantically related, the problem of orthogonally restricting aspects occurs. We elaborate on several solution approaches, namely object-oriented design approach, aspect-oriented design approach, and composition of events and actions approach to tackle the history sensitivity evolution problems in a modular and reusable manner.
