CAD系统集成和集成技术剖析

系统集成能从根本上解决工程CAD技术应用中的分散独立和低水平重复问题，是进一步发掘计算机潜力的有效途径。文章以集成化的桥梁CAD系统的开发为背景，提出了由界面、工具和数据等三个层次组成的桥梁集成CAD系统结构，并针对软件工业的最新发展介绍了实现CAD系统集成的软件开发技术，包括面向对象的程序设计、图形界面和基础类库、软件构件化开发及数据库图形库连接等。

Integration of Bridge CAD System and Integration Technologies

The system integration can essentially solve the problem of isolated and repeated on low level development which is common now in the field of engineering CAD technology application，and is an effective way to exploit the potential of computer further．On the background of the development for a new generation bridge CAD system，this paper gives the system architecture of the integrated bridge CAD system which consists of the user interface，tools and data，the three level integration．And this paper also introduces the software development technology which could be employed to approach the integrated engineering CAD system，include the object oriented programming，graphical user interface and foundation class library，component software development and database and graphics system connection etc．which are all the state－of－the－art according to the current state of the development of software industry．
