The design and implementation of unstructured data management system in e-learning teaching system
Xiaopu Wang · 2010
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.
