Teaching System Design And Implementation Based On Smart Client

In recent years, with the multimedia technology and the rapid development of network technology, Internet has become the main carrier of information, with the rapid development of modern education, distance learning has become a new mode of transmission of knowledge into people's lives. Distance learning can maximize use of existing teaching resources, flexibility, across time and space to complete th e study, training, examination and so on. More than the current distance education system based on B/S mode system, which is characterized by good services, eas y maintenance, easy to deploy, in the distance learning has been widely used. How ever, distance education system based on B/S mode, found a few disappointment s, mainly reflected in:must be connected to the network, not in the offline state o f learning; difficult to achieve real-time communication and information exchanges d elay; If there is a large number of concurrent users in the network to access the d atabase server will affect the system response time, user experience is not good; th e performance of the limited capacity of the interface is not conducive to diversit y course of the expansion of the network. In order to overcome the current distance education platform systems that exist in the practical application of limited functio nality, poor performance an other defects, through exploration and research, we pro pose a development of Java-based smart client network teaching system.This Papers according to Beijing University Institute of Educational Technolog Pr oject "National Science & Technology Pillar Program—Intelligent direction and man agement of virtual experiment system" and proposed Java-based smart client remote t eaching system, and explain some technologies of the model. Based on Smart Client' s distance learning system can speed up the user requests the response speed and redu ce server processing load, and can achieve a powerful user interface, data security acce ss, you can achieve centralized deployment and automatic updates, the most important thing is to support working both online and offline status...
