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。

AM-Notebook is a multi-featured tabbed note-taking program that provides an easy and reliable way to save notes and formula supported spreadsheets in a light weight tray icon tool.

上午的笔记本是一个多精选分页注意回吐的程序提供了一个非常简单和可靠的方式来保存自己的注释和公式，试算表支持在一个重量轻，托盘图标的工具。

Fdisk is not only a zoning process, it has a very convenient feature to restore the main boot sector, but only modify the main boot sector, other sectors of the write operation is not carried out, so for those who are still using Windows 9x friend the case of no doubt is a very good tool to repair the partition table.

Fdisk 不仅是一个分区程序，它还有着非常便捷的恢复主引导扇区功能，而且它只修改主引导扇区，对其他扇区并不进行写操作，因此对于那些还在使用 Windows 9x 的朋友而言无疑是个非常理想的分区表修复工具。

Thereforemyself unify the ticket clerk to sell the management the request, toMS SQL the Server2000 database, Microsoft Visual Basic 6.0, AdobePhotoshop 7.0 has carried on a more thorough study and theapplication, fully uses the object-oriented design method mainly tocomplete gets a light from another light the station ticket clerk tosell the management system management system the demand investigationand study analysis, the function module division, the database patternanalysis as well as the data dictionary establishment and themaintenance, and has developed the database table structure and theapplication procedure from this the design.

因此本人结合票务销售管理的要求，对MS SQL Server2000数据库、Microsoft Visual Basic 6.0、Adobe Photoshop 7.0进行了较深入的学习和应用，充分利用面向对象的设计办法主要解决对火车站票务销售管理系统的需求调研分析、功能模块划分、数据库模式分析以及数据字典的建立和维护，并由此设计开发了数据库表结构和应用程序。

When the user loads an equation with n variables (up to 6), the application automatically builds up a table with one line per variable.

Based on the characteristics of parameterized design and key technologies of knowledge based engineering, and specially according to the characteristics of the construction, figure, assembly-parameter of bicycle frame design, the article has achieved repeated using of experiential parameter and knowledge by adopting methods such as automatic reading experiential datasheet, computing parameter by making use of program, manual data-input or modifying and so on. Based on analyzing the characteristics of Rear End design and the associated characteristics with Chain Stay and Seat Stay, different design methods are analyzed in detail, and rapidly assembling of Rear End, Chain Stay and Seat Stay is achieved by using the method of combining top-down-assembly with down-top-assembly method. Based on analyzing special technologies and UDF characteristics, the repeated using of different sectional shapes by using UDF technology on the tube section design is also achieved, and this will greatly shorten the time spent on fixing the dimensions and orientations on sketches.
