基于分布式的文件服务器数据库加锁与刷新构件的设计

The Design of File-sever-based Add-lock-and-refresh Component Based on DDB

解决了有关文件服务器数据库加锁与刷新构件的设计问题：客户－服务器方式在用户量或网络数据量较少的情况下的执行效率并不如分布式文件服务器方式的效率高，文章在从理论上讨论有关网络数据库的隔离机制和锁定和刷新方式的基础上，提出了一个通用的基于分布式文件服务器的锁定和刷新构件的设计方案。

This paper proposes a method of how to design file-sever-based add-lock-and-refresh component.The client-sever mode's efficiency is lower than the file sever mode when the number of user or the network data flow is small.The paper firstly discusses the isolation mechanism and lock-refresh mode of the net-based database,then brings out a design of file sever-based add-lock-and-refresh component.
