【摘要】 随着网络应用对数据库的访问量日益增大,数据库管理系统(DBMS)受到越来越多的关注。自主计算的研究解决了DBMS内部资源管理的问题,但是无法解决外部负载的管理问题;不同的负载具有不同的商业价值,具有重要商业价值的负载其性能要求应当优先得到满足。将针对负载自适应技术开展研究,提出一个改进的数据库负载自适应体系结构框架并作出了测试。结果表明该框架起到了提高用户满意率的作用。更多还原

【Abstract】 With the increment of visit traffic to database from network application,the data base management system(DBMS) has caused extensive concern.The research of autonomic computing has resolved the inside resource administration problem of DBMS,but it has no way to solve the one of outside workload administration.Different workload have different commercial va-lue.Whose function demands the workload which has important commercial value ought to have priority to satisfied.This paper solved the difficult problem with study on workload adaptation,proposed and tested WAAD(workload adaptation architecture for DBMS).The experimental result indicates that this frame can enhance the satisfaction of users.更多还原
