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 systems 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。

The main contents and results of research in this paper are shown as following: It is important to built the motion model of a virtual system. As the virtual object is the submarine in this simulation system, we studied on the motion model of the submarine and gave the submarine six DOF space motion equation MultiGen-Paradigm corporation's modeling software named Creator is used, the modeling of all entities and 3D terrain in virtual ocean environment is accomplished. Then introduced the theory of Large Area Database Management and realized the Large area database management; In the course of 3D scene simulation, Vega is utilized to develop the project. The building of 3D scene is done, which includes the simulation of static and dynamic ocean surface, realization of ocean wave, simulation of bow wave and stern wake, utilization of lighting and material, simulation of cloud and fog, kinematics' modeling of submarine etc.
