| 摘 要： | 从分析面向对象数据库中对象模型、数据依赖着手，提出了对象函数依赖的概念，在此基础上提出了以分解为基础的对象模式、规范化方法，并在分析对象模型、关系模型的基础上，介绍了用四元组的方式研究这两种模型的表述关系以及关系模型可以用对象模型完全描述的结论，据此，给出了关系模型与对象模型间的映射关系，通过简单实例，探讨了关系模型中嵌入对象机制的可行性

| Abstract: | Based on the analysis of object model and data dependency in OODB , the concept of object function dependency is presented, and the normalization method of object model is given,in which main idea is decomposition.Based on the analysis of object model and relation model , the way of quadtuple to study the modelling of these two models is introduced and the conclusion that relation model can be described by object model is provided . From the analysis above , the mapping relationship from relation database to object database is created . By the simple demo , the implementation possibility that object system is embeded in relation data model is analysised . |
