> 中文摘要: 随着电子产品迅速发展,设计涉及的信息量日益增大,数据格式种类繁多,工程和设计数据管理系统已越来越成为电子产品CAD框架的关键构成部分.本文提出以面向对象方法管理框架系统中的工程和设计数据,对其中的关键部分数据模型作了研究,并给出了DDL实现.该系统已应用到电子CAD框架系统中。
Abstract:As electronic products developing rapidly,the information of the design is in-creasing and requires a more powerful data management system.The engineering design data management system is a crucial component in an ECAD framework when the design involves large volume of data in diversified format.This paper identifies the requirements for such a system and presents the approaches that support these requirements.This paper presents a data model and its corresponding DDL.This system is currently under develop-ment and will be released in the next generation of the electronic products ECAD frame-work.
