摘要
介绍了一个弱一致性的复制数据库系统WCSR。WCSR系统支持服务器的移动性与断接,采用Read-Any-Write-Any复制范型,通过周期同步方式维护系统的一致性(并发事务的Epsilon-可串性),并且支持可变一致性的事务处理,因此非常适合于移动计算环境。
This paper presents a weakly consistent replicated database system, called WCSR. WCSR supports mobile server and its disconnection, provides Read-Any-Write-Any replication for databases, and maintains consistency (Epsilon-serializability) by Periodic pairwise synchronization. WCSR can also support variable-consistency transaction processing. Finally, we argue that WCSR is suitable for mobile computing environments.
