查询词典 underlying database

We only consider the operation system, the applied software on client machine, net and other hardware etc., When tuning the database performance with traditional way. If we only tune the database's round environment, it just respited the situation, and could not resolve the problem at all.

传统的数据库性能优化主要从操作系统、客户端应用软件程序设计、网络及其它硬件设备等方面来考虑，这种方法只是调整数据库的周边环境，只能暂时缓解问题，而不能从根本上解决问题。

Experimental study had been carried out by using Mandarin emotional speech database recoded and emotional speech database respectively.

Then the algorithm was used to get the seven parameters of viscosity model of W-Ni-Fe heavy alloy and 316L stainless steel feedstock, which provide the necessary material data for quality forecast of mold core part made of stainless steel and heavy alloy tungsten ball, and for optimal design of mold and process parameters, which establishes the foundation of material database of MIM. In the research of visual simulation software development, in order to build the software system model and flow analysis algorithm based on Cross-WLF viscosity model, and realize functions such as pre-processor, solver, parameter regress, data management, graph operations, some advanced software methods as OOSE (Object Oriented Software Engineering) and UML were applied to set up user model, static model and dynamic model of MIM simulation software. These models describe system function, event flow, structure and relation of classes, object interaction, structure of database and I/O file format.

在MIM可视化仿真软件开发方面，为了建立软件系统模型及基于Cross-WLF粘度模型的流动分析算法，实现软件的前处理、求解器、参数拟合、数据管理和图形操作等功能，将面向对象软件工程与统一建模语言技术首次引入到MIM仿真软件的设计开发中，建立了软件的用户模型、静态模型和动态模型，描述了系统的功能需求、事件流程、类的结构与关系、对象之间的通信、数据库结构和输入输出文件格式等，用Visual C++与Delphi开发工具编码实现了2维MIM充模流动过程仿真软件，方便了对薄壁零件的质量预测以及模具和工艺参数的优化设计。

The transaction manager mechanism is responsible for the system concurrency through the two-phase lock and time-span deadlock detection. The lock unit achieves object-level. With the help of the database diary and AI file, it provides strong ability to recover from various database breakdowns.

事务管理机构通过两阶段锁定和超时死锁检测，完成各站点用户对数据库访问的并发控制，其封锁粒度达到对象级；通过日志记录和后备文件AI，实现系统强有力的故障恢复功能。

From ORACLE system structure, the paper organizes and allocates memory with SGA and PGA. The key of performance tuning is to confirm the hit ratio of system. The ORACLE system's store structure includes physicial structure and logical structure. So , it is the basis to decide the size of tablespace, data file and control file. The database object includes index, cluster, views and store procedure etc., the object have important effect on database. Lastly, it contrasts the ways of Based on Cost and Based on Rule and organizes the SQL under SQL/PLUS system environment.

本文从目前的医院信息系统现状分析，提出系统性能评价指标，并从ORACLE体系结构出发，对内存区中的系统全局区及程序全局区进行合理的组织与分配，确定合理的命中率，这是性能优化的关键；ORACLE存储结构采用的互为关系的逻辑存储结构与物理存储结构，故确定其中的表空间、数据文件、控制文件的大小是性能优化的基础；数据库对象结构中的索引、簇、视图、存储过程等对其进行合理的设计，对大型数据库的性能有着重要的影响；最后便是在SQL／PLUS境下，通过与基于代价与基于规则的方法进行比较，对合理高效的SQL语句进行组织，并列出优化后系统性能的情况。
