【摘要】 随着分布式对象计算技术研究的深入 ,分布式多用户数据共享协同控制中有待解决的关键问题是环境的异构性、数据的一致性、操作的并发性。本文以政务信息共享平台为应用研究背景,针对政务信息共享平台中空间数据共享的特征提出了一种基于多AGENT多用户协同工作机制的解决方案,文中给出了基于多AGENT的协同工作机制的体系结构、多用户分布式数据库访问协同控制方法和主-次AGENT协同工作模式的设计。并给出了解决由于多用户同时操作可能产生的操作冲突,及破坏系统一致性问题的实现方法。更多还原

【Abstract】 With the further development of Distributed Object Computing technology, there still remain some key problems in the collaborative control in distributed multi-user data sharing: heterogeneous environment, data consistency and concurrent operation. According to the characteristic of spatial data sharing, we put forward a certain kind of solution based on multi-agent collaborative working mechanism in the background of government affairs information sharing platform. In this paper, cooperative working mechanism and the multi-user access controlling method of distributed database are analyzed, and the design of cooperative model is shown. We also describe the implementation method to solve the possible problems created by multi-user cooperation.更多还原
