面向对象的关系数据库及其在汽车车身设计中的应用

Object Oriented Relational Database and Application in Vehicle Body Design

目的研究车身ＣＡＤ中的数据分析与管理．方法采用面向对象（ｏｂｊｅｃｔ－ｏｒｉｅｎｔ－ｅｄ，简称Ｏ－Ｏ）的方法，以车身设计工程数据库为例，阐述了采用面向对象方法进行数据库建模的步骤，归纳了将面向对象的分析结果转化为关系数据库模型的方法．结果建立了车身ＣＡＤ数据库及其管理系统．结论实用证明，按照Ｏ－Ｏ方法建立的车身ＣＡＤ数据库能较好地支持车身设计过程．

Aim To carry out research on data analysis and management of vehicle body CAD Methods The main method was O O (object oriented) The steps of database O O modeling were presented by means of the analysis and design of vehicle body engineering database The rules of transforming the O O model to relational database model were also presented Results The vehicle body CAD database and its management system were established Conclusion The practice shows that the vehicle body CAD database established by means of O O method can support the body design course easily
