面向中小机构的文件管理系统的设计与实现

DESIGN AND IMPLEMENTATION OF DOCUMENT MANAGEMENT SYSTEM FOR SMALL AND MEDIUM-SIZED INSTITUTIONS

针对目前中小机构对文件管理的需求,分析当前网盘存在的问题,设计研发一款操作便捷、管理有效的轻量级文件管理系统。该系统采用标签技术对文件进行分类和检索,通过虚拟文件层和SHA-1算法实现了文件去重和资源回收,利用分布式的版本控制思想有效地解决了多用户情况下文件版本控制问题,保证了用户访问数据的一致性,实现了网络文件存储、文档协同修改、多用户共享文件等功能。实际应用情况表明,系统能够有效地管理和共享文件,实现多用户协同工作,对重复文件能够自动检测和删除,大大提高了存储资源和网络资源的利用率,降低了资源管理复杂度。

Targeted at the requirement of medium and small-sized institutions on documents management at present, we analyse current problems of network disks, and present in this paper a light-weighted document management system which is convenient in operation and effective in management. The system classifies and retrieves documents with tagging technique, and achieves files deduplication and resources recovery through virtual file layer and SHA-1 algorithm, h uses the idea of distributed version control to effectively solve the problem of document version control among multiple users, guarantees the＇ consistency of users data access, and realises the functions of network files storage, document collaborative amendment, and multi-user document sharing, etc. Actual application situations of the system demonstrate that it can effectively manage and share files, achieves multi-user cooperative work, and can automatically detect and delete duplicate files, these greatly increase the utilisation of storage and network resources, and reduce the complexity of resource management as well.
