摘要: 飞机载荷谱数据库平台的媒体管理系统相对于一般网站管理系统,存在着媒体文件数量多,分类关系庞杂的特点。针对这些特点,有两个需要解决的难点:第一,把媒体文件合理分类,优化媒体文件分类检索关联,以实现快速查看;第二,用户浏览多个分类的媒体文件时,需要多次加载页面,浪费了系统和网络资源。若采用Ajax技术实现请求数据的异步动态加载,一些不变的数据避免了被多次重复加载,减少了每次用户请求所需传送的数据量,达到了快速响应的用户体验。

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
