Cloud-based Digital Library Construction Research

September 2009 organized by the Academic Committee of China Society for Library Science "Cloud Computing and Libraries " workshop held in Shanghai, marking the official involved in the library community of cloud computing. With the development of libraries, more and more scholars begin to pay attention to the concept of cloud computing business of implantable digital library.20th century, 90 years, network technology breakthrough, the formation of digital information environment, globalization, digital library construction boom, highlighting the awareness of library services, gave birth to a new digital library services, cloud forms. The emergence of cloud computing will allow continuation of a century of library service that takes the form jump. Cloud computing technology not only greatly enriched the theory of library science, and the extension of new and extended areas of library practice.Cloud computing books in the country by the intelligence community great concern, cloud computing has become a grid computing model can not be ignored and business computing environment. At present, China Academic Library and Information System (China Academic Library Information System, CALIS) technology center to support the development of CALIS Distributed Digital Library of cloud services cloud services platform has been initially completed, the new generation of digital library system development and implementation of the lay A new technology base. Cloud computing will become a new bright spot in digital library services.However, an overview of domestic and international digital library of cloud development, domestic and foreign in every respect there is a big gap, which for historical reasons, there are practical reasons. In recent years, digital libraries in China has made remarkable progress in industry, but because of the lag network infrastructure and the quality of personnel constraints, etc., many of our low level of digital library services, has most of the cloud-based library The project has not yet been started. For the purposes of Jilin Province, there is no cloud of a formal service. Analysis of the reasons to think the solution in an attempt to cloud service development of digital libraries and digital libraries play a role in facilitating this is the object of this study and efforts.In this paper, the development of cloud computing at home and abroad and the present status as the starting point, the main contents are as follows:Chapter 1, Introduction. Paper outlines the background, purpose and significance of research and describes the development of domestic and international status of cloud computing and cloud computing research in digital libraries.Chapter 2, cloud computing, an overview of relevant theories and key technologies. Associated with the thesis of the theory are reviewed, discussed the concept of cloud computing, cloud characteristics of the environment, the architecture of cloud computing, cloud computing and other computing relations and its implementation mechanisms.Chapter 3, cloud computing, the impact of digital libraries. Analysis of cloud computing major impact on digital libraries. Firstly, the cloud the value of the digital library; Secondly, the analysis of the current development of digital libraries problems; Again, the analysis of cloud computing the functional advantages of digital library; Finally, the importance of the digital library based on cloud computing Pavilion has a certain risk must be careful.Chapter 4, the cloud-based methods and strategies to achieve digital library. Discuss the cloud-based digital library practice methods and strategies. First, the logic level from the analysis of the feasibility of its implementation, and analysis of specific cloud computing architecture of digital libraries; then describes the digital library content and characteristics of cloud services; Finally, the construction of digital libraries cloud computing strategy. Chapter 5, the digital library system to build the cloud evolution. From the perspective of empirical research, the design of the Digital Library of the virtual cloud computing resource pool configuration, database server architecture, database access mechanism, the application server architecture, and network platform architecture and so on. Further verify the implementation of the Digital Library of cloud computing feasibility and operability.Chapter 6, the conclusions and prospects. Summary of the whole thesis, put forward the issue for further research, and prospects cloud prospects for the development of digital libraries.Currently most of the scholars on the Digital Library of the cloud base remains at the theoretical level and the feasibility study level, the lack of the digital library system from the perspective of the evolution of the specific implementation of cloud computing research. This is not only a comprehensive analysis of the current development of digital libraries in China the main problems, but also through the cloud in the Digital Library summarized the value of the functional advantages of cloud computing. On this basis, is designed based on cloud computing architecture of digital libraries and digital library is proposed to the cloud evolution strategy.From the perspective of empirical research, the design of the Digital Library of the virtual cloud computing resource pool configuration, database server architecture, database access mechanism, the application server architecture, and network platform architecture and so on. Further verify the implementation of the Digital Library of cloud computing feasibility and operability. In this paper, a system designed to focus on solving the outstanding problems in current digital libraries, in raising the degree of virtualization, the integration of information resources and the resources have unique advantages, these are also papers innovation lies.Building a successful digital library services based on cloud computing system is a long and arduous task, not only professionals in libraries, computer aspects of personnel is also essential. Which gives a new era of digital reference service has brought new challenges, just keep on learning and exploring, be possible to adapt to the new situation on the reference development. The development of modern information technology for the digital library service model brings an opportunity to optimize the digital library service model optimized for the needs of modern information technology to support the integrated use of the concept of cloud computing services to optimize the strategy, pushes strategy, specific Strategy, the strategic integration of personal contact, supplemented by traditional digital library service, to demand a given service. Digital Library for the realization of the core values, needs, based on the traditional service, absorbing the idea of cloud computing, with the use of information technology, information services, new thoughts formed a new service strategy. Also need to retain some of the traditional service mode, with the new service strategies, multiple methods, the formation of virtualization, fast, personalized, efficient service delivery model, high quality of library service to the user's ultimate goal.
