According to introducing, the meeting after these baleful trojan programs affect tube-shaped part of computer science department undertakes to the system of a lot of destroy, be like: Without the license of computer user bowdlerism or it is file of the mass data in replacing interconnected system of computer science department, cause the important data in maintaining existence system to the file is lost or be distorted.

据介绍，这些恶意木马程序感染计算机系统后会对系统进行很多的破坏，如：未经计算机用户的许可而任意删除或是替换计算机系统中大量数据文件，造成保存在系统中重要的数据文件丢失或被篡改。

The meeting after these baleful trojan programs affect tube-shaped part of computer science department undertakes destructive to the system, like the license without computer user bowdlerism or it is file of the mass data in replacing interconnected system of computer science department, cause the important data in maintaining existence system to the file is lost or be distorted.

这些恶意木马程序感染计算机系统后会对系统进行破坏，如未经计算机用户的许可而任意删除或是替换计算机系统中大量数据文件，造成保存在系统中重要的数据文件丢失或被篡改。

The personal file system is a typical information management system, is a practical C/S structure unit edition personal file administrative system.

摘 要：人事档案系统是典型的信息管理系统，是一个实用的C/S结构单机版人事档案管理管理系统。

This paper discusses the organizing principle of knowledge library in expert system and suggest that the Sequential File, Index File, Multichain File, Backcomposing File, Hash File, etc can be adopted to organize knowledge library and the corresponding program is designed in the Prolog Language.

论述了专家系统中知识库的组织原则，对在计算机上如何实现知识库的物理组织问题，提出可以采用顺序文件、索引文件、多重链接表文件、倒排文件及散列文件等方法来组织知识库。

Since daemons normally exist until the system is rebooted, if the daemon stays on a mounted file system, that file system cannot be unmounted.

如果你的守护进程是挂载到文件系统上的，那这个文件系统就不能卸载掉。

Through sharing file between mainframe system and open system, these heterogeneous systems can realize unseaming integration basd on data and mutual operating basd on file system. It has great significance for combining of storage resources and taking a good advantage of the abundant application programs having existed on mainframe system and reducing the cost of data storing.

通过大型机系统与UNIX服务器、Windows服务器等开放系统之间的异构文件共享，各系统能在数据层面上实现无缝集成以及在文件系统的层面上实现交互，对于存储资源的整合、充分利用大型机已有的丰富业务软件以及降低企业的数据存储成本都具有十分重要的意义。

For the coherence in metadata, a serverless architecture model based on all the data and metadata is adopted because they can be storaged in all place and can be dynamicly transferred; The associative mode of the disc metadata's journal structure and the memory metadata's journal structure can turn away the timing waste in scanning the enormous file system by fsck; Afterwards a intercalating checkpoint algorithm and a rollback recovery algorithm based on the metadata fault tolerance in cluster file system is implemented; A fetched stochastic process model is setup to analyze availability of this system, it can reduce the inspecting fault time and then they support high availability.

为了达到复杂的元数据管理一致性，采用了一个无集中式服务器的体系结构，保证所有的数据和元数据能够存放到系统的任意地方，并且在操作的过程中可以动态迁移；采用元数据的磁盘日志结构和内存日志结构相结合的方式对元数据进行管理，减少了fsck对庞大的文件系统中元数据的扫描时间；为了实现故障恢复，提出了元数据容错的设置检查点算法和回卷恢复的算法，提高了文件系统元数据服务的可用性；给出了基于元数据故障的随机过程模型，可以通过减少检错时间提高文件系统的可用度。

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。
