The Applicaiton Model Research Of Digital Libarry Based On Cloud Computing Environment

With the rapid development of network technology and computer technology,information penetrates to the social fields in rapid and an unprecedented situation, theperformance of information is more and more rich, now, documentation, image, audio,video and other multimedia information become the indispensable element to constructdigital library, the main research content of this subject is how to make theseinformation security effective utilization and management, how to set up digital librarywhich is convenient, rich in content and information sharing, the traditional servicemodel has been ragged. In this context, new service calculation mode-cloud computingwhich based on distributed computing can meet the needs of the construction of digitallibrary, so it will become the new trend of the development of digital library.Cloud computing is a internet application mode put forward by Google, which isthe realization of some computer science concept in the internet, such as distributedprocessing, parallel processing and grid computing. But along with the development ofthe web2.0technology, digital library is also more used the idea and the technology ofweb2.0, which used to improve their own service, expanding the high-end complexnetwork application, to the library2.0ahead. Therefore, adopting the cloud computingmodel as the underlying architecture of digital library can greatly improve the library'sservice in software environment, the application platform, data sharing and otheraspects, which is the best solution. But, to cloud computing in the early stage, there aremany immature and discuss place when they application in the library, and theparticularly important is how to make sure the information resources security, so, wemust think carefully about the security risk which cloud computing will bring, so thatwe can cope with the possible challenges easy.Whatever in foreign countries or in domestic, cloud computing in the research onthe application of digital libraries has just started, it is must use different methods in theresearch progress of home and abroad to start the research of the construction of thedigital library based on cloud computing, which can achieve a comprehensive andin-depth research purposes. Cloud computing will make the digital library undergoingprofound change in software environment, the hardware store, application platform andservices methods. In the cloud computing applications process, in order to ensure thesecurity of the digital library information resources, it is should be gradually establishand perfect the relevant industry standards, making ensure the safety of the informationresources storage, realizing the information resources confidentiality and integrity,strengthen authority into user access control.The purpose of this paper is to construct a complete set of digital library cloudservice system based on cloud computing. Specific content includes: analyzing thepresent situation of the domestic and foreign digital library and cloud computingapplications development in system, introducing the related theories and concepts about the research; analyzing and researching the contents and characteristics of the demandof digital library users, discussing the service system structure and operation of thecloud model of digital library, designing function module of the digital library cloudservice mode; Finally, this paper giving a empirical research about the system designedto verify its feasibility...
