Design and Implementation of Business Logic Layer Object-Oriented Design versus Relational Design

摘要

Object-oriented programming has become one of the mainstream programming paradigms in software engineering, whereas relational models are predominant in commercial data processing applications. There is strong competition between these models for dominance in the building of modern applications, especially after the emergence and spread of object-relational mapping technology. This paper addresses the question of whether the object-oriented approach is better than the traditional approach in terms of flexibility with respect to changing requirements.
