摘要
随着分布式应用与实时系统的发展,分布式实时数据库系统的研究引起了人们的关注;而事务的并发控制,则是研究的重点.通过对Web的全排序性、可预测性、缓存性等特性的分析,提出了用于分布式实时数据库的并发控制算法.提出的基于可预测性的算法是自适应的,有助于增加事务满足其截止期限的可能性.
With the development of the distributed application and real-time system, more and more people pay attention to the studies of the distributed real-time database system. Concurrency control of transactions is the emphasis of such study. The algorithm of concurrency control in the distributed real-time database system is presented by analysis of Web properties, such as totally ordering, predictability, caching and so on. The presented algorithm based on predictability is adaptive, helpfully increasing the possibility of meeting the deadline of transactions.
