面向对象应用的数据库原形系统的研究

RESEARCH ON THE DATABASE PROTOTYPE SYSTEM OF THE OBJECT- ORIENTED APPLICATION

本文提出了一种通过扩充概念模型来实现面向对象的数据库原型系统(Prototype System of OODB)的思想.文中阐述了POODB的层次结构和模块结构,讨论了从EER模型到关系模型的转换,给出了系统中的两个核心模块——可视化数据定义模块和数据字典管理模块的实现技术.

The article puts forward an approach to realize a prototype system of the object-oriented database (POODB) by extending conceptual model. It expounds the hierachical structure and the module structure in the POODB. Also it discusses the transfer from ERR to relation model. At last, it gives the realizing way of two kernel modules -visualable data definition module and data dictionary managment module.
