【摘要】:本課題研究一種基于云存儲(chǔ)的數(shù)字圖書(shū)館資源存儲(chǔ)模型。本課題所研究的系統(tǒng)模型是在深入研究數(shù)字圖書(shū)館資源建設(shè)和云存儲(chǔ)技術(shù)的基礎(chǔ)上,并根據(jù)現(xiàn)有圖書(shū)館的業(yè)務(wù)需求提出一種基于云存儲(chǔ)的模型設(shè)計(jì)方案。 本文的研究?jī)?nèi)容有如下幾個(gè)方面: 1.對(duì)現(xiàn)有的數(shù)字圖書(shū)館資源的存儲(chǔ)模型進(jìn)行分析研究: 通過(guò)對(duì)傳統(tǒng)的資源存儲(chǔ)方式的優(yōu)缺點(diǎn)進(jìn)行分析,結(jié)合數(shù)字圖書(shū)館資源存儲(chǔ)發(fā)展的需要,分析數(shù)字圖書(shū)館的存儲(chǔ)特點(diǎn)以及所需要的存儲(chǔ)技術(shù)。數(shù)字圖書(shū)館正在向區(qū)域性、聯(lián)合性發(fā)展,通過(guò)資源的整合并統(tǒng)一的對(duì)外提供服務(wù),實(shí)現(xiàn)跨行業(yè)、跨地域的資源有限和服務(wù)無(wú)限,資源的共享深度和廣度出現(xiàn)前所未有的景象,真正讓用戶感覺(jué)到信息資源的高度共享和無(wú)處不再得服務(wù)。 2.把云存儲(chǔ)理論的思想引入數(shù)字圖書(shū)館的資源存儲(chǔ)中 在眾多的存儲(chǔ)技術(shù)中,云存儲(chǔ)技術(shù)脫穎而出,云存儲(chǔ)具有分布式文件系統(tǒng)、網(wǎng)格技術(shù)和集群應(yīng)用等功能,通過(guò)應(yīng)用軟件將大量處在網(wǎng)絡(luò)中的各種不同類型的存儲(chǔ)設(shè)備集合起來(lái)協(xié)同工作,虛擬成一個(gè)系統(tǒng)統(tǒng)一對(duì)外提供數(shù)據(jù)訪問(wèn)和數(shù)據(jù)存儲(chǔ)服務(wù)。云存儲(chǔ)像互聯(lián)網(wǎng)和廣域網(wǎng)一樣具有云狀的結(jié)構(gòu),對(duì)于使用云存儲(chǔ)的用戶來(lái)講,不是具體的指某一設(shè)備,而是指有很多服務(wù)器和云存儲(chǔ)設(shè)備所構(gòu)成的集合體,云存儲(chǔ)的使用者,使用的并不是某一具體的存儲(chǔ)設(shè)備而是整個(gè)云存儲(chǔ)系統(tǒng)虛擬的資源,是一種數(shù)據(jù)訪問(wèn)服務(wù)。云存儲(chǔ)的核心是存儲(chǔ)設(shè)備與應(yīng)用軟件相結(jié)合,通過(guò)應(yīng)用軟件來(lái)實(shí)現(xiàn)存儲(chǔ)設(shè)備向存儲(chǔ)服務(wù)的轉(zhuǎn)變,也方便了對(duì)存儲(chǔ)設(shè)備的管理。 3.對(duì)云存儲(chǔ)中副本存放的策略進(jìn)行改進(jìn) 通過(guò)分析HDFS分布式文件系統(tǒng)文件副本存放策略,并對(duì)HDFS副本存放策略進(jìn)行改進(jìn),提出動(dòng)態(tài)副本存儲(chǔ)策略。 4.設(shè)計(jì)符合數(shù)字圖書(shū)館資源存儲(chǔ)的系統(tǒng)模型 云存儲(chǔ)的技術(shù)非常適合數(shù)字圖書(shū)館資源的存儲(chǔ),區(qū)域性的數(shù)字圖書(shū)館統(tǒng)一的接口和云存儲(chǔ)的統(tǒng)一的數(shù)據(jù)服務(wù)非常相似,所有的資源都存儲(chǔ)在云中從而能更方便資源的共享,數(shù)據(jù)的管理、維護(hù)都更方便,本文通過(guò)對(duì)現(xiàn)有的圖書(shū)館存儲(chǔ)技術(shù)和云存儲(chǔ)技術(shù)的分析,設(shè)計(jì)出一個(gè)符合數(shù)字圖書(shū)館資源存儲(chǔ)發(fā)展需求的云存儲(chǔ)模型,,并實(shí)現(xiàn)模型中的部分功能。通過(guò)對(duì)所實(shí)現(xiàn)的功能進(jìn)行性能測(cè)試,從實(shí)驗(yàn)結(jié)果證明模型的可行性、優(yōu)越性。
[Abstract]:This paper studies a digital library resource storage model based on cloud storage. The system model studied in this paper is based on the research of digital library resource construction and cloud storage technology, and according to the business needs of the existing library, a model design scheme based on cloud storage is put forward. The research contents of this paper are as follows: 1. Analysis of the existing storage model of digital library resources: through the analysis of the advantages and disadvantages of the traditional resource storage, Combined with the needs of the development of digital library resource storage, the storage characteristics and storage technology of digital library are analyzed. The digital library is developing to the regional, joint development, through the integration of resources and unified external services, the realization of cross-industry, cross-regional resources and unlimited services, the depth and breadth of resource sharing has never been seen. 2. Introducing cloud storage theory into the storage of resources in digital libraries in many storage technologies, Cloud storage technology stands out. Cloud storage has the functions of distributed file system, grid technology and cluster application. Virtual system provides data access and data storage services. Cloud storage, like the Internet and WAN, has a cloud structure. For users who use cloud storage, it does not refer specifically to a particular device, but to a collection of many servers and cloud storage devices, the users of cloud storage. It is not a specific storage device, but a virtual resource of the whole cloud storage system. It is a data access service. The core of cloud storage is the combination of storage device and application software to realize the transformation from storage device to storage service through application software. It also facilitates the management of storage devices. 3. To improve the strategy of copy storage in cloud storage by analyzing the file copy storage strategy of HDFS distributed file system and improving the policy of HDFS copy storage. The strategy of dynamic copy storage is put forward. 4. The technology of cloud storage, which accords with the system model of digital library resource storage, is very suitable for the storage of digital library resources. The unified interface of the regional digital library is very similar to the unified data service stored in the cloud. All resources are stored in the cloud so that it is more convenient to share the resources, and the management and maintenance of the data are more convenient. Based on the analysis of the existing library storage technology and cloud storage technology, this paper designs a cloud storage model that meets the needs of the development of digital library resource storage, and realizes some functions of the model. The experimental results show the feasibility and superiority of the model.
