基于移动应用的图书馆服务设计与实现——以“国家数字图书馆”移动应用为例

Mobile Application Service Design and Implementation in the Library-Taking the Application Named’the National Digital Library’As an Example

移动应用属于一种客户端形式的服务。在线类移动应用基于C/S架构，在其设计与实现中要从客户端和服务器端两个方面考虑，并进行性能优化，尤其是客户端与服务端的交互实现。“国家数字图书馆”移动应用将检索服务、阅读服务等图书馆基础服务拓展到移动终端，并与开放平台进行融合，实现了外部功能在图书馆系统中的嵌入式服务。将具有移动应用特色的信息推送服务引入到图书馆移动服务中，当有最新消息时，为读者提供更新通知。同时使用widget技术，将书目检索与阅读服务功能做成桌面插件形式，用户可以将之放到桌面，“一键式”使用具体服务功能。
