Based Distance Learning Management System Of The Web, Research And Development

As a representation of contemporary education, remote education, which has brought the traditional education revolutionary ideas and technologies and optimized the educational resources, has been the trend of the contemporary education. Remote education can't run well without an efficient management platform. With the development of Internet technology, Web-based remote education has been the latest tendency of remote education. And taking into account the conditions of software and hardware in Central South University, it is the best choice to design and develop a Web-based remote education management platform to support different kinds of multimedia courseware based on Web.The paper introduces the detailed process of the design and development of the platform of management and supporting system consisted of an asynchronous education management and supporting system and a synchronous one.The system is divided into six parts: control of loging in, system management, test through network, real-time chating, homework management and free forum. Using Microsoft NetMeeting technology to realize the synchronous remote education, the system was designed with the three-tier Brower/Server model, which uses ASP as the middle-ware. And the server contains the Web server and the Database server. The platform is Microsoft Windows 2000 Advanced Server (with IIS 5.0) and MS SQL Server 2000.The system is developed by ASP technology, a kind of new technology of the Web dynamic technologies, which can form homepage dynamically using the server scripts and implement-many functions when being used with the ActiveX components. Open Database Connectivity (ODBC), a technology that uses SQL to communicate with a data source through ODBC drivers interpreting the SQL and translating it for use with a particular database format, and ActiveX Data Objects (ADO) which enables users to write an application to access and manipulate data in a database server through an OLE DB data provider is used to access background database. It also discusses the technologies in the multilevel Security and performance optimization of the system.The paper introduces the system from the following aspects: the design target and teaching model, the technology project of development, the design and implement, the key technologies, the security and optimization of performance.
