摘要
In the Engine CAD application system engineering database management system (ECAD-EDBMS) is the kernel. ECAD-EDBMS can manage and process the multimedia such as graphics, data, text, sound, image and video. It provides the integrated environment and more functions for many subsystems of ECAD and engine designers. So it improves the design efficiency.
在以工程数据库为核心的发动机CAD系统中，工程数据库管理系统（ECAD－EDBMS）除管理图形和数据外，还能提供文字、声音、图像、影像等信息媒体的管理操作功能，为CAD系统中多个子系统开发和发动机设计者提供多媒体支持环境，提高工作效率．
