Abstract: Compared with ordinary website management systems, the aircraft load spectrum database platform media management system is characterized by a much larger number of media files and much more complex relationships between them, which makes it hard to carry out their classification. Accordingly, two difficult issues need to be addressed: First, realize the logical classification of media files and optimize their association to enable fast localization of them when searching operations is triggered; second, when users are browsing multiple classes of media files, they may need to request multiple pages constantly that results in redundant network data transferring and a waste of system resources. These can be solved by using Ajax technology to load data asynchronous and dynamically to avoid repeated loading of unchanged data, so that the amount of data required for transferring and the load of Web server is reduced and fast response is realized at the client end.

Key words: Ajax, media management system, aircraft, load spectrum, Web2.0
