基于Web的分布式数据库实时访问策略研究
Study on Real-time Access in Distributed Database Based on Web
【摘要】 基于Web的分布式数据库管理与控制是目前数据库研究的一个热点领域。针对用户要求及事务实时性的特点,分析了传统实时网络数据库访问的文件加锁、缓冲区设置、数据管理与更新方法,提出了结合虚拟锁机制的二阶段加锁方法的一种新机制,有效地解决了用户的实时访问与并发控制问题。
【Abstract】 The management and the control of distributed database which is based on the Web are a hot spot domain in the present study of database. In view of user request and the real time character of the affair, this paper analyzed the traditional idea of accessing the real time network database, such as locking the files, setting the buffer, managing and updating the data. Meanwhile, combining with the two staged adding lock idea based on the hypothesized lock mechanism,these works can solve effectively with the problems: real time accessing and concurrency control to the database.
