The Research And Implemention Of Network File Management System Based On Web Service

With the rise of cloud computing and cloud storage, the traditional file management systembased on the specific Protocol NFS, CIFS, FTP is be unfit for the Internet Share through varietyof different terminal. The network file manager is the new research field in the network storagemanagement application which can manage the organization internal files effectively andeconomically. Its traditional products internal file sharing storage products NAS wereproverbially used in varies field. According to lack of the browser based on network filemanagement system, this paper in reference to the WebDAV file level locking offers advancedconcurrent access to the function of the protection and integrates general file server capacity todesign and develop file management system based on the HTTP.Through researches of the relevant theoretical, based on the analysis of the overall businessrequirements and the system characteristics, the thesis uses Web Service and.NET technique todesign and realize the network file management system. This paper applied tier architecturedesign concepts and software engineering methods. It analysis the system design architecturethrough use case and Sequence diagram elements, designs and realizes all module. It usesTransaction Pattern find all the entity class. It uses Web Service to envelope the substrate servicein order to archive relax coupling of layers and calling cross-platform. Additionally, in therealization of the file upload, using IHttpModule interface to provide the module file upload theimplementation of the initialization and disposal events, solving the general file upload can’tbreak out of limited capacity and high takes up the server resources faults.After testing, the thesis enables the network file management system works with friendlyinterface, smooth operation, upload file download performance. Which meets business ofinternal work requirements? Finally, this paper analyzes the research results of significance, andputs forward to further improve the efficiency improvement direction, and the futuredevelopment was discussed.
