【摘要】：云計算在學校信息化建設中的不斷應用,使得同類數(shù)據(jù)庫資源,類型和規(guī)模也呈現(xiàn)出不斷擴張趨勢,造成集中式數(shù)據(jù)存儲過大,服務器維護不易,容錯率逐漸減弱等事故經(jīng)常發(fā)生,系統(tǒng)實際拓展性能較弱,這不僅造成了資源浪費,也增加了現(xiàn)有多個系統(tǒng)整合難度,從而間接影響了用戶的體驗。面對掌上智慧校園日趨復雜的應用需求,如何對資源進行整合,提供優(yōu)質(zhì)的校園服務已經(jīng)成為掌上智慧校園亟需解決的問題。本研究在利用云計算相關服務模式下,對掌上智慧校園系統(tǒng)進行系統(tǒng)設計和實現(xiàn),將有效實施云計算在高校信息化建設中的運用,將信息化進程真正運用到高校教學,科研實踐中,為營造高效智慧校園系統(tǒng)提供技術支撐。論文首先結合高校的實際情況,通過用例圖的方式表示了系統(tǒng)的業(yè)務需求,然后描述出了系統(tǒng)的總體架構圖,系統(tǒng)分為基礎信息服務平臺和掌上智慧校園終端兩個主要部分,最后設計并實現(xiàn)了基于云計算的掌上智慧校園系統(tǒng)。具體而言,分三步進行詳細的設計與實現(xiàn):第一是采用基于云存儲的Hadoop開源解決方案,能夠快捷地將學校各種計算機硬件資源搭建成為一個Hadoop集群,不僅實現(xiàn)了分布式存儲系統(tǒng),也實現(xiàn)了基于MapReduce編程模型的大規(guī)模數(shù)據(jù)集并行計算。第二是通過WebService技術搭建了基礎信息服務平臺,能夠將學校不同的應用系統(tǒng)的異構數(shù)據(jù)整合起來。第三通過B/S模式設計了基于WEB的掌上智慧校園終端,可讓用戶使用瀏覽器直接訪問。新設計并實現(xiàn)的掌上智慧校園系統(tǒng)針對高校目前的資源利用現(xiàn)狀,結合云計算技術和程序開發(fā)、軟件設計等相關技術,搭建了云計算環(huán)境下的智慧校園系統(tǒng),為學校師生提供了一個手機掌上智慧校園。
[Abstract]:With the continuous application of cloud computing in school information construction, the same kind of database resources, types and scales also show a trend of continuous expansion, resulting in excessive centralized data storage, difficult server maintenance, gradual weakening of fault tolerance and other accidents, and the actual expansion performance of the system is weak, which not only results in waste of resources, but also increases the difficulty of integration of existing systems, thus indirectly affecting the experience of users. In the face of the increasingly complex application needs of the handheld intelligent campus, how to integrate the resources and provide high-quality campus services has become an urgent problem to be solved in the handheld intelligent campus. This study uses cloud computing related service mode to design and implement the handheld intelligent campus system, which will effectively implement the application of cloud computing in the information construction of colleges and universities, and truly apply the information process to the teaching and scientific research practice of colleges and universities, so as to provide technical support for the construction of efficient intelligent campus system. First of all, combined with the actual situation of colleges and universities, this paper represents the business requirements of the system through use case diagram, and then describes the overall architecture of the system. The system is divided into two main parts: the basic information service platform and the handheld intelligent campus terminal. Finally, the handheld intelligent campus system based on cloud computing is designed and implemented. Specifically, the detailed design and implementation are carried out in three steps: first, the Hadoop open source solution based on cloud storage is adopted, which can quickly build all kinds of computer hardware resources into a Hadoop cluster, which not only realizes the distributed storage system, but also realizes the parallel computing of large-scale datasets based on MapReduce programming model. The second is to build the basic information service platform through WebService technology, which can integrate the heterogeneous data of different school application systems. Third, a handheld intelligent campus terminal based on WEB is designed through B / S mode, which can be accessed directly by browser. According to the present situation of resource utilization in colleges and universities, combined with cloud computing technology, program development, software design and other related technologies, the intelligent campus system in cloud computing environment is built, which provides a mobile phone handheld intelligent campus for school teachers and students.
