The Design Of Educational Administration System Of University Based On Virtual And Web Teaching

The educational administration is the most important work for colleges anduniversities. It refers to universities, colleges, teachers, students,student-records, administrations and so on. Along with the reform and themerger of colleges and universities and the enrollment expansion of suchinstitutions, colleges and universities have adopted the academic credit systemand the elective course system. At present, colleges and universities require acomplete set of teaching administration system to manage the administrativework. The information administration initialed earlier in the European andAmerica countries, where the application and popularization of the informationadministration are relatively more mature than that in China. The informationconstruction in domestic colleges and universities started lately in our country.Colleges and universities early concentrated on the investment in acquisitionand construction of computer hardware and the network, gradually carried outthe development and construction of the information system based on thenetwork,and developed and deployed some management application systems,such as teaching, academic research, and office work. The informationconstruction has formed certain scale. However, the educational administrationinformation in China lags behind in all aspects compared with that in foreigncountries due to many reasons, for instant, the imperfect theoretical system, theshortage of fund input and the underestimation of the educationaladministration information. The system of “the educational administration platform in universities” is the application software system concerning teachingand the educational administration in universities and colleges. Proceedingfrom the reality of the educational administration, it should give full play to thesupport ability of the computer’s network and the advantages of central store ofthe information and the network sharing for the aim at realizing the educationalinformation management during the whole process, and helping teaching stufffree from the complex and inefficient work.This article focuses on the development of object-oriented thinking ofapplications-"Web-based Teaching Administration Platform of the University "，the methods and processes, ranging from feasibility studies to the system putinto use mainly related to the document. That describes the object-orientedanalysis and design methods and tools, and advanced. NET technologysystems design and implementation. The system was developed based on. NetFramework3.5platform, using ASP.NET+SQL Server2005technology, sixmodes (GM layer, physical layer, interface layer, data access layer, businesslayer, presentation layer) for development。There are four layers between thedata access layer (SQLDAL) and the presentation layer (WEB), namely: thephysical layer (Model), the universal layer (Common), the interface layer (IDAL),the business layer (BLL). These six layers are independent from each other.The change of one layer does not affect any other’s functions.universal layer ofthe main Responsible for the entire class is stored in application developmentare used in the method of each layer, physical layer is responsible for carryingdata, the interface layer is responsible for defining some interface to access thedatabase data access layer is responsible for the operation of some of the data,business Layer is responsible for the entire system platform business logic,presentation layer is responsible for interaction with the user. Development environment for Dreamweaver+Microsoft Visual Studio. NET2008. Userinterface design using Dreamweaver, use Microsoft Visual Studio. NET2008toachieve the logic code.Through the technology of ASP.NET, developers of the web page can useHTML or XML to design and format the final page. Using ASP to generatedynamic content on the page, and executing the script on the client side willgreatly reduce the task of the server, which can help the server to get rid of theheavy transaction processing. Firstly, the client sends requests to the serverthrough a browser. IIS (Internet Information Services), upon requests,distributes them to the corresponding Aspx pages to deal with. After the serverfinishes processing the client’s requests, the results will be sent back to thebrowser in the form of HTML pages and display in the screen. when the clientsends requests to the server, the form of the whole client page is sent to theserver, so that a lot of bandwidth in the communication process is occupied,and the server’s task is increased. In order to resolve this problem, AJAX(Asynchronous JavaScript and XML) technology is applied. It can refreshpartially, which means that the client does not always send the entire page, andthe request is sent to the client for processing as XMLhttpResponse object torealize partial refreshing.The system divids into the role of administrators, teachers, and students.Admin (super user) enters the background after logging, whereas ordinaryusers (ordinary administrators, students, teachers) enter the front page (thefunction module of the foreground they see is set in the background by Admin,and it is dynamic display)。Admin can maintain the data dictionary in thebackground (e.g. course maintenance), and it also can maintain the departure,the personnel, the role, and the log. After logging, the user in the foreground will see the corresponding module according to its role. Among them, theadministrator can publish the news (other users can read the news after thelogon), manage the work of students and teachers, and develop teachingprograms. Students can examine course results, course elections, andindividuals’ transcripts, and export all the items mentioned above. Teachers canexamine and input students’ academic records.This system of university organizations, student record, teacherinformation, student achievement, student curriculum, lesson plans, informationrelease management, and to achieve a report printing function. As a result ofobject-oriented technology, and six design patterns, the system reached amodular, easy expansion and maintenance of the design requirements. Thesystem is beneficial to colleges and universities to carry out their business,improve work efficiency, enhance work quality, so that the office staff canquickly and easily complete the task of the educational administration. It makesthe educational administration more systematic, standardized, and automated,thereby enhancing the efficiency of the educational administration.
