摘要
协同CAD系统是支持多用户协同设计的CAD系统 文中提出了基于数据库的协同设计模型 该模型支持同步和异步方式的合作 ,采用数据库来管理共享信息和协作信息 利用数据库触发器设计使数据库具有主动服务功能 ,而利用通信机制实现了服务器的主动服务 ,有效地支持了协作共享和实时同步 对协作管理着重讨论了角色管理、任务管理和数据管理 ,其中对数据管理主要讨论了数据共享、群体感知和版本问题 。
Collaborative CAD system is a CAD system supporting multi user cooperative design. The model of database based cooperative design is presented. The model supports synchronous and asynchronous cooperation. The shared data and policies are managed by database. The active services of database are realized by database trigger and the active services of server are realized by communication mechanism. It supports effectively cooperative awareness and real synchronism. The cooperative management includes role management, task management and data management. The focus is put on the shared data, group awareness and colophon management in data management and some solutions are presented.
