Multimedia Teaching And Information Management System Design And Implementation

Multimedia technology and computer technology, audio and video technology, image compression technology and processing technology, the computer processing the information, media diversification. Multimedia system can handle information including text, graphics, images, music, voice, video and animation and other forms of modern information management, to bring a new face. Institutions of higher learning basic information management is an important task.Nowadays, as the Internet becomes more and more involved in higher education, and the more complex information, and information format, information content is very big. The traditional information management has become increasingly can not meet the demand, contradiction is more and more outstanding. The traditional multimedia information management adopted by the majority of the client / server (C / S) mode or a simple file storage mode, this mode of multimedia teaching, and hinders the resources sharing in the university. And maintenance cost, inconvenience of upgrading and many other factors, these factors influence the popularity of multimedia teaching in Colleges and universities.In this article the university multimedia teaching information management system is mainly studied using Internet / Intranet advantage, to realize the multimedia information management in the electronic, networking, and makes the system easier, management and maintenance more convenient, especially the data query is more flexible, convenient, greatly reduces the requirements on the client ( only need to run a standard browser ). But in the Intranet environment, the network security has greatly improved, with the Internet connection, network access is not subject to geographical constraints, so that the network expansion easier, and on this basis a fusion of image, audio, video, animation, multimedia processing technology as well as the image, audio, video, animation and multimedia storage technology, easier to multimedia information query, greatly expand the information sharing degree.And the university multimedia teaching information management system has good versatility and good maintainability, in data query depth, breadth have a greatly improved, based on the nonstandard format handling and storage. At the same time in the database design and the system architecture has many improvements; system is based on four layer architecture, display layer, business layer, data persistence layer, data layer, thus ensuring the system has low degree of coupling. The system transplant, then upgrade provided a guarantee. Database design using the PB implementation, this to database changes can achieve good control.
