| 摘 要： | 本文介绍了一个用Ｔｕｒｂｏ Ｃ语言在ＡＳＴ－２８６机器上实现的计算机辅助数据库设计系统ＣＡＤ＾２Ｂ。该系统提供了人机交互的环境，供设计者进行概念模型设计，并自动完成从概念模型逻辑模型的映射，创建满足规范化要求的关系表。该系统采用的概念模型是引入了事件和时间的扩展了的实体关系模型。该模型既能充分反映应用环境的静态和动态语义，又是向关系模式转化的基础。

| Abstract: | A computer-aided database design system CAD2B in using Turbo C on AST-286 is introduced in this paper. The system provides users with a mam-machine interactive environment for conceptual modelling. The system can do mapping auto-matically from conceptual model to logical model and create relational tables in accord with demands of normalization. The conceptual model mentioned in the system has adopted events and time so that the semantics (static and dynamic) of application environments can be fully expressed and the model becomes the base to map to relational schema. |
