数据文件

This paper analyzed data from multiple sources and different structures, concluded three types of info: Login info, Event info, and Packet data info, then created the formation for every type of data; In order to combine future possible new data, IDS using profile and formation string together, create and practice data formation standard algorithm; Because in the collected data, there is info that is redundant or has minor effect on the IDS, this paper discussed the rules of redundant data differentiating and safe data differentiating, Then create data filter rule base; Data collecting system uses distributivity design, collecting module like a black box. we can get data which was filterd and had standard formation, if we created a new model string for new data source. Module work individually; filter data right away at the collecting node.

本文分析了多种来源的、不同结构的数据，将其总结成登录信息、事件信息和网络数据包信息三种类型，并为每种类型的数据设计了固定的格式；为了与将来可能出现的新型数据兼容，采用了配置文件与模式字符串相结合的方法，设计并实现了数据格式标准化算法；由于收集到的数据中存在冗余的信息和对入侵检测影响不大的信息，本文分别讨论了冗余数据辨别规则和安全数据辨别规则，并建立起数据过滤规则库；数据收集系统采用分布式设计，收集器以黑盒形式提供，对新的数据源只需设计一个新的模式字符串，即可得到过滤后的、具有标准格式的数据，各收集器间独立工作；在收集点即对数据进行过滤，只向分析中心报告可疑数据，以减少传输和存储的数据量，降低对网络性能的影响。

To build this file system, an atomic updating algorithm and a mult－buffer coheront policy are presented. Based on time－stamp, using variable－size blocks of files, the atomic updating algorithm controls the modification operations on the replicated files.

所设计的分布式文件系统用来支持分布式全局进程调度，它具有如下特点：（1）既支持分布式单副本文件的管理、又支持分布式多副本文件的管理；（2）被访问的文件数据缓存在客户侧结点机；（3）文件互斥访问的粒度为变长访问块；（4）提供全局一致的文件命名空间和透明文件访问能力；（5）支持用户在系统中任一结点机注册；为实现本文件系统，笔者提出了原子更新算法和多缓存一致性策略。

Information is stored in mass storage systems in large units called files. A typical file may consist of a complete text document, a photograph, a program, or a collection of data about the employees in a company. The physical properties of mass storage devices dictate that these files be stored and retrieved in multiple byte units. For example, each sector on a magnetic disk must be manipulated as one continuous string of bits. A block of data conforming to the physical characteristics of a storage device is called a physical record. Thus , a file stored in mass storage will typically consist of many physical records.

在大容量存储系统中，信息是以称为文件的大的单位储存的，一个典型的文件可以是一个全文本的资料，一张照片或一组关于公司员工的数据，大容量存储系统的物理特性表明，这些文件是按照许多字节为单位存储的检索的，例如，磁盘上每个扇区必须作为一个连续的二进制位串进行操作，符合存储系统物理特性的数据块称为物理记录，因此存放在大容量存储系统中的文件通常包含许多物理记录。

Comparing with the existing cache technology, the accelerating system based on the data stream cache technology does not result to obtain outdated files and does not retransfer the file that is little change with the primary file.

与现有的缓存技术相比，数据流缓存技术不会存在提取过时文件和文件中小部分变化而仍要重传的问题，同时还解决了文件中重复数据的位置问题。

Divorcing file system metadata operations from actual file data operations improves immediate performance, but also improves long-term aspects of the file system such as recoverability and availability.

从实际文件数据操作中脱离文件系统元数据操作提升了即时性能，同时也提高了文件系统的长期的方面，例如可恢复性和可用性。

Discrete control points being a information description object, a datasheet can be designed to include all kinds of coordinate data, coordinate explanation data, station occupation description data, file data of a single point, stored in the form of sequential file.

以离散的点位为信息表示对象，将一个点的各种坐标数据、坐标说明数据、测站描述数据、文件数据等设计在一张数据单中，并以顺序文件形式存储。

A new method for indexing large amounts of points inhigh-dimensional space is proposed.The basic principle is as follows:uniformly partition the data space by Lattice vector quantization,store the lattice points by Inverted File,organize the inverted file by Trie tree,and fast access the inverted file by Trie parallel search algorithm.

本文提出一种新的高维空间中点数据的索引方法，其基本原理是用格矢量量化均匀划分数据空间、用倒排文件存储格点、用Trie树实现倒排文件的组织和存储、用Trie并行搜索算法实现倒排文件的快速访问。

The regular file inodes hold references to objects on OSTs that store the file data instead of references to the actual file data itself.

正常的文件inodes有指向对象的引用on OTS，它存储文件数据而不是指向实际的文件数据的引用。

It the file such as the only evidence in of all kinds system, bill translates an user into file of EDI standard format, traffic, commerce, carry, the business data such as custom, carry electronic special railway line or Email mail, undertake with format of EDIFACT of ／ of international standard UN data is exchanged, the syntactic regulation that consolidates according to international undertakes handling to message, it is a kind of new business that handles work quickly through the computer.

它把用户各类系统中的单证、票据等文件翻译成EDI标准格式文件，将交通、贸易、运输、海关等业务数据，通过电子专线或Email邮件，以国际标准UN／EDIFACT格式进行数据交换，并按照国际统一的语法规则对报文进行处理，是一种通过计算机迅速处理事务的新业务。EDI具有快速、及时、廉价、安全、不受时空限制等优点，它降低了人工操作的错误率，提高办事效率减少纸张文件的消耗，改善了客户服务质量。

This brought fixed cost, but it also is meant at the same time use a source to won't make you singlehanded assume a problem.

这带来了一定的成本，但它同时也意味着使用开源不会让你独力承担问题。
