Object Oriented Design Based on Role and Rule

Internet brings more flexibility and possibilities to software. How to develop and maintain the software conveniently and easily is a big challenge for the developers of Internet applications. The purpose of this paper is to create a systemic framework for object oriented design (OOD) and map between the program and the reality. This paper investigates the things, relations and interactions between things, and defines a set of concepts: universal, particular, perspective, perspective transfer, nature, feature, rule and triggering mechanism. These concepts are used to explain the basic structure of the framework. Some important problems in object oriented programming (OOP) and aspect oriented programming (AOP) are investigated in detail. A prototype system has been implemented and tested. The experiments prove that the new thought is realistic and efficient.
