摘　　要：如何实现数据库的协同机制,使其更好支持群组交互的应用是当前数据库技术面临的一大挑战。该文讨论了如何在面向对象数据库中引入协同机制,并解决可能遇到的问题。文章在阐述了如何实现协同工作的过程中按照分层的方式,由低层到高层的顺序依次递进。各层都有清晰的定义和明确的控制目标,最终可以完成复杂的协同任务。A great challenge toward database technology is present now.How to design the cooperation mechanism of object oriented database,and support the group operation and interaction has already become a highlighted issue.This paper discusses the topic of how to introduce cooperation mechanism into database and how to solve some foreseeable problems.In terms of describing how to implement the cooperation within database,the paper first defines the hierarchies of the task,then sequentially goes through them.In every hierarch,there are clear definition and distinct target of control.Based on this,a complicated cooperation job can be completed.
