一种基于设计过程的附加式工程数据库系统的研究与设计

Research and Design on an Attached Engineering Database System Based on Design Process

针对传统ＣＡＤ系统在设计信息管理上的薄弱环节，提出了一种基于设计过程的附加式工程数据库系统，将工程数据库通过应用程序和数据接口附加在ＣＡＤ系统上，通过二者的有机结合，实现了设计过程中的数据动态实时交换和在线加载，达到了数据共享、重用以及集成化、结构化管理的目的。附加式工程数据库的应用增强了ＣＡＤ功能，提高了设计效率和质量。

To solve the problem on design information management of traditional CAD system,the paper presents an attached engineering database system based on design process:the engineering database is attached on the CAD system through application program and data interface,the data is exchanged dynamically and loaded online in design process, and is shared,reused and managed in integration and structure. The efficiency and quality of CAD are enhanced with the application of the attached engineering database.
