摘要
ONet是一个基于C/S体系结构的对象数据库管理系统,其中的并发控制和缓冲一致性问题关系着整个系统的架构和实现。ONet采用自适应的多粒度锁缓冲算法为基础,并进行相应调整,对其页面修改合并方法进行改进。该锁缓冲算法能够根据系统的冲突频繁度动态选择并发控制的粒度和客户端数据拷贝的管理粒度,使得并发效率和数据共享度均有显著提高。
ONet is an object database management system based on client/server architecture. The concurrency control and cache consistencyofONetarefocusedon. First, the adaptive call-back lock algorithm was introduced, and then an improved page update-merger method was proposed. This algorithm could adaptively adjust the granularity of concurrency control and cache based on concurrency conflict degree, thus it could achieve quit a good performance.
