摘 要:以元数据为基础的文件管理系统将丰富的元数据和文件进行关联,有效地提高了文件查询速度,但元数据管理服务独立于目录系统,两个系统难以同步.为此,基于第一性原理,采用自下而上的设计哲学,以文件为中心,提出了注记文件系统,即先有文件再向文件添加注记的方式将文件和其描述信息进行关联,使文件目录系统和元数据注记系统合二为一.注记表示为文件的描述信息,注记文件系统将目录信息转化为注记,在解决多分类文件目录创建困难的同时提高了文件的查询效率.在目录系统和注记文件系统下文件查询过程中以文件比较次数为依据,对两种系统进行了理论分析和实验验证,结果表明注记文件系统在文件查询上效率更高.The metadata based file management system,which associated the rich metadata and file together,can effectively improve the speed of file query.However,metadata management services are independent of directory systems,making it difficult to synchronize these two systems.Based on the first principle,the bottom-up design philosophy is adopted and the files are taken as the center.The annotating file system hence is proposed,that is,the file is associated with its description information by adding annotations to the file first,so as to combine the file catalog system and metadata annotating system into one system.Annotation indicates the description of a file.Annotation file system converts directory structure information into annotation,which solves the difficulty of creating multi-class file directory and improves the efficiency of file query.Based on the number of file comparison between directory system and annotation file system,theoretical analysis and experimental verification are carried out for these two systems.The results show that annotation file system is more efficient in file query.
