Construction And Intelligent Application Of The Courseware Material Storehouse

The modern Distance Education is an important supplement and development of traditional education. It plays more and more significant role in the social progress and the development of the human civilization. The courseware material storehouse as an important component of the Distance Education, especially the application of the new technology in the courseware material storehouse, such as its construction way, network technology and multimedia technology, etc., have already become the key target of present research.The target of the thesis is to realize the platform of courseware material storehouse based on Web. It has managed effectively to material resources, plain source of courseware, offered online teaching courses, and opened users' BBS. It helps to search material resources of the courseware variously fast, offers an intelligent guide for computer users. It implements back-stage management to the courseware material database and well realizes the management and maintenance of the courseware and material of multimedia. It has realized the cross-platform interchanging data and the resource-sharing of the courseware material storehouse through the integrated network service and expanding the uploading-downloading module.The key points of the thesis are as follows:1 Construction technology of the courseware material storehouse on the basis of Web. It has explored the application of B/S. C/S mode in the system and establishing the connection between .NET frame and platform.2 Proceeded the beneficial study to Metadata standard with realizes. According to 《The Technique Norm》 .combined to consults the model of LOM & Dublin core, use structuralized information to describe the multimedia material.3 The design, management and maintenance of courseware material database. It has explored the expanding from the relevant database to multimedia database and the access mechanism of binary scale file of multimedia data in the database, and optimize the group's storehouse tactics. Establish a strong back-stage management of courseware material database, which can manage effectively the multimedia material.4 Fast search of the multimedia data. It has probed the searching way of multimedia data, realized the abstraction of the multimedia data information and designed the many kinds of searching scheme such as brief searching, associated searching, full-text searching, catalogue tree searching etc. , which can realize a high-efficient, intelligent and fast searching of multimedia data.5 The application of XML technology in the construction of the courseware material storehouse platform. It has probed the function of XMLtechnology in the aspect of standardizing and opening the platform as well as the technology and realization of XML page turning in Web, and Web database in the process of chaining and interchanging.
