摘 要：随着信息技术的飞速发展和互联网技术的不断完善，用户处理和接触的数据不断膨胀，以及数据的安全性，数据的管理和维护的成本的不断提高的同时，出现了一种全新的存储技术—云储存（Cloud Storage）。传统的数据储存方式已经不能满足现在用户的使用，主要的缺点是：成本高，数据易丢失，安全性差，不方便管理。   本课题对基于云储存展开了深入细致的研究和设计，初步探索并实现了B/S模式的云储存文件管理系统的各个几大主要功能模块。该系统以JAVA高级开发语言为核心开发语言，实现了用户对于文件的上传和下载，以及对文件的增删改查基本操作，并且还可以进行文件分类查看，新建文件夹，文件重命名，个人账户中的文件数据统计分析等高级操作。课题研究成果经过改进后可以直接在商业项目中使用。例如学校办公系统的文件管理，个人文件的储存和管理，工业数据储存和管理，网络资源的储存和管理，医院就医数据的储存和管理等，商业应用前景相当广泛。92478

Abstract：With the rapid development of information technology and the continuous improvement of Internet technology, and expansion of user processing and contact data ,as well as data security, data management and maintenance costs continuing to improve at the same time,  a new storage technology - cloud storage (Cloud Storage) emerges。The traditional way of data storage has been unable to meet the needs of users for its high cost ,easily lost data,poor security and inconvenient management。The topic has carried out on the deep study and design based on Cloud storage, and initially explored and realized some major functional modules of B/S of Cloud storage file management system。The system uses JAVA as the main development language。 And the system has realized some advanced operations ,which include not only that users can upload and download files ,but can check the classification of files , set new folder,rename files and statistical analysis of files of personal account 。The achievements of this study which have been improved can be directly used in commercial projects ,like file management of school office system, the storage and management of personal files and industrial data, resource of network and data of hospital 。The commercial application of this system will be used widely in the future 。
