Users with advanced knowledge of physical design structures can use this tool to perform exploratory database tuning analysis 对物理设计结构很熟悉的用户可使用此工具执行探索性数据库优化分析。
Database tuning novices can also use the tool to find the best configuration of physical design structures for the workloads they tune 数据库优化初学者也可使用此工具为其优化的工作负荷找到最佳物理设计结构配置。
You can start the database engine tuning advisor graphical user interface in several different ways to support database tuning in a variety of scenarios 可以用几种不同的方式启动数据库引擎优化顾问图形用户界面( gui ) ,以支持不同情况下的数据库优化。
With opc data information accessing technology and configuration software operate it , this system stores the real time data collected from dcs into database . and with the optimized database statistic management , the system can issues the production data report on web , and supervises the real time locale parameters of product line with dynamic web pages 系统将集散控制系统站采集到的实时生产数据,通过数据信息访问技术和组态软件operateit将数据存储到数据库中,再经数据库优化的统计管理,用web的方式发布生产数据报表,并以动态网页的形式对生产线现场的实时数据参数进行监视。
Then , according to some algorithm , the optimizing processor can determine which node among the system is the best to execute this query . the whole system is based on mysql , an open source database , which is widely used in internet application . the balance of this paper is organized as following : the first chapter reviews the progress of the distributed database 全文分为六章:第一章对分布式数据库做总体概述,第二章回顾了数据库优化技术的发展,第三章介绍了本文基于的数据库系统模型dpsql ,第四章在分析分布式数据库查询执行的基础上对基于局域网的分布式系统进行了优化研究,第五章是对第四章讨论的优化的实现,第六章对优化系统做了性能上的分析和探讨,最后的结语总结了全文。
