基于VBA的Auto CAD实时协同系统开发

Development of Auto CAD Based on VBA-time Collaborative System

采用了以集中式及分布式相结合的混合结构,设计了一个实时的设计系统,通过SQL2000数据库系统构建了一个网络图形数据库,将协同设计者关于图形信息操作记录存储至数据库中,完成数据的统一。同时,在各协同者之间,构建通信发送操作信息,触发接收模块,然后读取数据库信息作图,实现协同设计的目标。

This paper uses the combination of centralized and distributed hybrid structure,designed a real-time system design,SQL2000 database system through a network of graphic database was constructed,the designer will coordinate operations on the graphical information in the record store to the database,complete data unity.Also,coordination between the various build communication send operational information,trigger receiver module,and then read the database information mapping,to achieve the goal of collaborative design.
