【摘要】：教育信息化发展是现代教育发展的必然趋势,数字化校园建设作为信息化教育发展的重要途径,引起了各个高校的关注和重视。在数字化校园建设的背景下,各个部门业务系统地应用给学校的教学、科研和管理带来了极大的方便。但是我们不得不面临一个亟待解决的问题：各部门的业务系统各自为政,缺乏统一的规划和建设,导致了各部门业务系统之间无法实现有效的数据交换。校园数据中心的建设和数据交换技术的运作,能够在原有各个成熟系统基础之上实现各个部门数据的有效交换。真正实现了“多个入口、一个出口”的校园数据管理机制,保证了数据来源的权威性与统一性,使得各个部门的数据能够融会贯通、交换自如,从而打破了各个业务系统之间各自为政的状态,这种“信息孤岛”的现象也将随之消失。在西南交通大学数字化校园建设的环境下,本文主要从信息标准的建设、数据中心学生数据库的设计和数据交换这三个方面展开论文的叙述。首先对论文的研究背景、意义以及现状进行了详细的描述。第二部分对数字化校园数据中心做了概述,介绍了数字化校园的概念、理论基础以及校园数据中心建设原则。第三部分是对信息标准建设和数据交换的相关理论技术的概述。从信息标准的概念出发,对信息标准建设的原则和制定做了简要阐述。第四部分是全文的核心部分,对校园数据中心学生数据库的设计进行了详细阐述,在对整体分析设计基础之上,又从数据流图、表、视图、存储过程等方面详细分析了学生数据库的设计,并利用Power Designer建模工具设计了学生数据库的模型。最后对数据交换做了简要分析,以业务系统与数据中心对接为例,阐述了关系模式与XML模式之间相互映射的过程。
[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.
