摘要： 介绍了协同商业 ＣＡＤ系统（ＣＭＣＡＤＳ）中的协同设计模型。基于 ＳＱＬ Ｓｅｒｖｅｒ解决了协同设计模型设计中的并发控制、一致性保证和多用户界面等问题。由于可实现数据共享、并行设计，从而可缩短设计周期；而利用计算机进行协调又可减少协调时间并保证正确性。

Abstract: The model of cooperative design on collaborative market computer aided design systom(CMCADS) is introduced. Based on SQL Server, the problems of control, consistency enforcement and multi-user interface on cooperative design have been solved. The design cycle can be shortened by data sharing and concurrency design. Collaboration is solved by computer, collaborative time can be shortened.
