【摘要】：教育信息化發(fā)展是現(xiàn)代教育發(fā)展的必然趨勢(shì),數(shù)字化校園建設(shè)作為信息化教育發(fā)展的重要途徑,引起了各個(gè)高校的關(guān)注和重視。在數(shù)字化校園建設(shè)的背景下,各個(gè)部門業(yè)務(wù)系統(tǒng)地應(yīng)用給學(xué)校的教學(xué)、科研和管理帶來(lái)了極大的方便。但是我們不得不面臨一個(gè)亟待解決的問(wèn)題：各部門的業(yè)務(wù)系統(tǒng)各自為政,缺乏統(tǒng)一的規(guī)劃和建設(shè),導(dǎo)致了各部門業(yè)務(wù)系統(tǒng)之間無(wú)法實(shí)現(xiàn)有效的數(shù)據(jù)交換。校園數(shù)據(jù)中心的建設(shè)和數(shù)據(jù)交換技術(shù)的運(yùn)作,能夠在原有各個(gè)成熟系統(tǒng)基礎(chǔ)之上實(shí)現(xiàn)各個(gè)部門數(shù)據(jù)的有效交換。真正實(shí)現(xiàn)了“多個(gè)入口、一個(gè)出口”的校園數(shù)據(jù)管理機(jī)制,保證了數(shù)據(jù)來(lái)源的權(quán)威性與統(tǒng)一性,使得各個(gè)部門的數(shù)據(jù)能夠融會(huì)貫通、交換自如,從而打破了各個(gè)業(yè)務(wù)系統(tǒng)之間各自為政的狀態(tài),這種“信息孤島”的現(xiàn)象也將隨之消失。 在西南交通大學(xué)數(shù)字化校園建設(shè)的環(huán)境下,本文主要從信息標(biāo)準(zhǔn)的建設(shè)、數(shù)據(jù)中心學(xué)生數(shù)據(jù)庫(kù)的設(shè)計(jì)和數(shù)據(jù)交換這三個(gè)方面展開論文的敘述。首先對(duì)論文的研究背景、意義以及現(xiàn)狀進(jìn)行了詳細(xì)的描述。第二部分對(duì)數(shù)字化校園數(shù)據(jù)中心做了概述,介紹了數(shù)字化校園的概念、理論基礎(chǔ)以及校園數(shù)據(jù)中心建設(shè)原則。第三部分是對(duì)信息標(biāo)準(zhǔn)建設(shè)和數(shù)據(jù)交換的相關(guān)理論技術(shù)的概述。從信息標(biāo)準(zhǔn)的概念出發(fā),對(duì)信息標(biāo)準(zhǔn)建設(shè)的原則和制定做了簡(jiǎn)要闡述。第四部分是全文的核心部分,對(duì)校園數(shù)據(jù)中心學(xué)生數(shù)據(jù)庫(kù)的設(shè)計(jì)進(jìn)行了詳細(xì)闡述,在對(duì)整體分析設(shè)計(jì)基礎(chǔ)之上,又從數(shù)據(jù)流圖、表、視圖、存儲(chǔ)過(guò)程等方面詳細(xì)分析了學(xué)生數(shù)據(jù)庫(kù)的設(shè)計(jì),并利用Power Designer建模工具設(shè)計(jì)了學(xué)生數(shù)據(jù)庫(kù)的模型。最后對(duì)數(shù)據(jù)交換做了簡(jiǎn)要分析,以業(yè)務(wù)系統(tǒng)與數(shù)據(jù)中心對(duì)接為例,闡述了關(guān)系模式與XML模式之間相互映射的過(guò)程。
[Abstract]:The development of education informationization is the inevitable trend of the development of modern education, digital campus construction as an important way to the development of information technology education, has aroused the concern and attention of many colleges. The construction of digital campus in the background of various departments of the application systems for school teaching, scientific research and management has brought great convenience. But we have to face a problem to be solved: business systems lack of coordination of various departments, lack of unified planning and construction, resulting in between each department system to realize effective data exchange. According to the number of campus construction and data center switching operation, can in the original system on the basis of various mature to achieve effective exchange of each department data. The real implementation of the "multi campus entrance, a data management mechanism for export", to ensure that the data source of authority and unity, So that all sectors of the data can be integrated and exchanged freely, thus breaking the state of affairs between the various business systems, and the phenomenon of "information island" will also disappear.
In the construction of digital campus of Southwest Jiao Tong University environment, this paper mainly from the construction of information standard, design and data exchange center database of the students carried out the paper of the three aspects described. Firstly, research background of this thesis, a detailed description of the significance and the current situation. The second part is an overview of the digital campus data center, introduced. The concept of digital campus, campus data center construction theory and principles. The third part is an overview of relevant theories of information technology standard construction and data exchange. Starting from the concept of information standard, information on the standard construction principles and formulation are briefly described. The fourth part is the core part, design of campus data center the student database in detail, on the basis of the overall analysis and design, and from the data flow graph, table, view, storage etc. The detailed analysis of the design of student database, and designed the student database model using Power Designer modeling tool. Finally the data are briefly analyzed in exchange, business systems and docking data center as an example, describes the process of mapping between relational schema and XML schema.
