Design And Realization Of AJAX-Based Information System Of Internet Multimedia Resouce Management

AS the speedy development of information technology and the quick changes of internet technology in the 21st Century, new technologies and theories of Web Area are coming forth one after another. By the development of internet, the defects of this system founded on the conventional Web exploration mode shows more obvious, as tardiness of system respond, inability of extension, inconvenience of maintenance and imperfectness of customer experiences. The value of Ajax tech puts up outstandingly, in the process that the ordinary Web tech is changing into current Web 2.0 tech, and run pattern of C/S application is replaced by B/S architecture. There is a majority of advantages about using Ajax tech in Web application. It can not only highly reduce load of servers, but also improve inadequate friendliness in human-and-computer mutual communication when using J2EE Web application. At the meantime, Ajax tech has changed the former synchronous alternation mode into current asynchronous alternation mode, making page layout achieving data according to need at background and partly refurbishing at frontground. In that way, the bandwidth is saved and the quality of customer experience is enhanced.This essay, on the basis of literatures inland and oversea and items involving practice, theoretically introduces the origin, development and application status quo of Ajax tech, analyzes Ajax tech's key tech and way of dividing and cooperating and compares the traditional Web exploration mode with active Ajax-tech-basic exploration mode. At the same time, it also investigates Ajax's combination of MVC application and J2EE architecture, discusses series of coming influences and issues and generalizes technical principle, strongpoints and weakpoints of Ajax, and aims at the Ajax tech various questions meet in the application, proposes the corresponding solution. Practically, this paper presentates information system of international multimedia resource management in details. This system constructs an information center for international multimedia resource on B/S mode, and provides a platform to organize, format, control, divide and effectively manage kinds of multimedia resources. This essay reopens up the existing system by Ajax tech, improving system capability and satisfaction degree of consumers.
