摘　　要：针对e-learning教学系统非结构化数据管理中存在着文件系统和数据库记录的不一致性和非结构化文件信息不能直接提取的问题,提出了在数据库和文件系统相结合的管理模式基础上加入文件控制模块和元数据提取模块,构建了基于元数据的e-learning教学非结构化数据管理系统,实现了对e-learning教学系统中非结构化文件的统一管理和信息直接提取,减少了人工输入,提高了效率.The file system and database records are usually not consistent and unstructured data information can not be extracted directly in unstructured data management of e-learning teaching system. A method was presented with a file control module and a metadata extraction module added on the basis of the management mode of database combined file system,and an unstructured data management system based on metadata was constructed in e-learning teaching system. Through the system,unstructured data files in e-learning teaching systems can be managed in a unified manner and information can be extracted directly,thus reducing manual work and improving efficiency.
