【摘要】：云計(jì)算在學(xué)校信息化建設(shè)中的不斷應(yīng)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(kuò)張趨勢,造成集中式數(shù)據(jù)存儲(chǔ)過大,服務(wù)器維護(hù)不易,容錯(cuò)率逐漸減弱等事故經(jīng)常發(fā)生,系統(tǒng)實(shí)際拓展性能較弱,這不僅造成了資源浪費(fèi),也增加了現(xiàn)有多個(gè)系統(tǒng)整合難度,從而間接影響了用戶的體驗(yàn)。面對(duì)掌上智慧校園日趨復(fù)雜的應(yīng)用需求,如何對(duì)資源進(jìn)行整合,提供優(yōu)質(zhì)的校園服務(wù)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(jì)算相關(guān)服務(wù)模式下,對(duì)掌上智慧校園系統(tǒng)進(jìn)行系統(tǒng)設(shè)計(jì)和實(shí)現(xiàn),將有效實(shí)施云計(jì)算在高校信息化建設(shè)中的運(yùn)用,將信息化進(jìn)程真正運(yùn)用到高校教學(xué),科研實(shí)踐中,為營造高效智慧校園系統(tǒng)提供技術(shù)支撐。論文首先結(jié)合高校的實(shí)際情況,通過用例圖的方式表示了系統(tǒng)的業(yè)務(wù)需求,然后描述出了系統(tǒng)的總體架構(gòu)圖,系統(tǒng)分為基礎(chǔ)信息服務(wù)平臺(tái)和掌上智慧校園終端兩個(gè)主要部分,最后設(shè)計(jì)并實(shí)現(xiàn)了基于云計(jì)算的掌上智慧校園系統(tǒng)。具體而言,分三步進(jìn)行詳細(xì)的設(shè)計(jì)與實(shí)現(xiàn):第一是采用基于云存儲(chǔ)的Hadoop開源解決方案,能夠快捷地將學(xué)校各種計(jì)算機(jī)硬件資源搭建成為一個(gè)Hadoop集群,不僅實(shí)現(xiàn)了分布式存儲(chǔ)系統(tǒng),也實(shí)現(xiàn)了基于MapReduce編程模型的大規(guī)模數(shù)據(jù)集并行計(jì)算。第二是通過WebService技術(shù)搭建了基礎(chǔ)信息服務(wù)平臺(tái),能夠?qū)W(xué)校不同的應(yīng)用系統(tǒng)的異構(gòu)數(shù)據(jù)整合起來。第三通過B/S模式設(shè)計(jì)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(shè)計(jì)并實(shí)現(xiàn)的掌上智慧校園系統(tǒng)針對(duì)高校目前的資源利用現(xiàn)狀,結(jié)合云計(jì)算技術(shù)和程序開發(fā)、軟件設(shè)計(jì)等相關(guān)技術(shù),搭建了云計(jì)算環(huán)境下的智慧校園系統(tǒng),為學(xué)校師生提供了一個(gè)手機(jī)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.
