文献库的目的是为了使读者能更有效、快速的查找到所需要的文献,这就要考查文献的存贮形式和方法问题。文件是文献存贮的基本形式,对文献库的维护与检索等操作,最终都要转化为对文件的操作。这里的文件除包含“若干记录的集合体”这一概念外,更主要的是指与各记录紧密联接的一些“关系文件”,如索引文件、链接文件等。存取效率,关链在于文件组织。文件组织的形式有多种,按存贮设备类型是顺序存贮设备还是直接存取设备,以及处理方式是联机处理还是批处理来分,文件组织形式可分两大类:顺序文件和随机文件。文献库
The purpose of the document library is to enable the readers to find out the required documents more effectively and quickly, which is to examine the storage form and methodological issues of the documents. Document is the basic form of document storage, document library maintenance and retrieval and other operations, and ultimately have to translate into the operation of the document. In addition to the concept of “a collection of several records,” the document here mainly refers to some “relational documents” that are closely linked with records, such as index files and linked files. Access efficiency, the chain is the file organization. There are many forms of organization of a document, depending on whether the type of storage device is a sequential storage device or a direct access device, and whether the processing manner is online processing or batch processing. There are two types of file organization forms: sequential files and random files . Literature Library
